Fractions to Decimals

Twelve tells us we have 1 ten and 2 units. The 1 ten must go two digits to the left of the decimal. The 2 units need to go one digit to the left of the decimal. The number Fifteen tells us we have 1 ten and 5 units. Here the 1 ten goes two digits to the left of the decimal and the 5 units goes digit to the left of the decimal. The four thousands tell us the number must go three digits to the right of the decimal. Note that we are adding the two numbers. Knowing the position of each number we then get 12 + 15.004

Eighty-two tells us we have 8 tens and 2 units. The 8 tens must go two digits to the left of the decimal. The 2 units need to go one digit to the left of the decimal. The five hundredths tell us the number must go two digits to the right of the decimal. Knowing the position of each number we then get 82.05

Sixty-Seven tells us we have 6 tens and 7 units. The 6 tens must go two digits to the left of the decimal. The 7 units need to go one digit to the left of the decimal. The eight tenths need to go one digit to the right of the decimal. Now looking at Twenty-four we have 2 tens which will go two digits to the left of the decimal and 4 units which will go one digit to the left of the decimal. The seven hundredths tell us the number must go two digits to the right of the decimal. Finally, we are subtracting the two numbers. Knowing the position of each number we then get 67.8 - 24.07

Fifty-nine is the same as 5 tens and 9 units. As we have 5 ten, the number goes two digits to the left of a decimal. The 9 units then is placed one digit to the left of the decimal. The number six one thousandths tells us it must go three digits to the right of the decimal. Knowing the position of each number we then get 59.006

This number tells us we have 1 thousand which goes four digits to the left of a decimal. We also have 5 hundreds which goes three digits to the left of a decimal. Sixty tells us we have 6 tens which goes two digits to the left of a decimal and 4 units tells us the number goes one digit to the left of a decimal. Finally, we have 2 hundredths which tells us the number goes two digits to the right of a decimal. Knowing the placement of each number we then get 1,564.02

Seventy-four tells us we have 7 tens and 4 units. The 7 tens must go two digits to the left of the decimal. The 4 units need to go one digit to the left of the decimal. The three tenths need to go one digit to the right of the decimal. Now looking at Sixty-four we have 6 tens which will go two digits to the left of the decimal and 4 units which will go one digit to the left of the decimal. The three tenths tell us the number must go one digit to the right of the decimal. Finally, we are subtracting the two numbers. Knowing the position of each number we then get 74.3 - 64.3

Forty-six tells us we have 4 tens and 6 units. The 4 tens must go two digits to the left of the decimal. The 6 units need to go one digit to the left of the decimal. The one tenth needs to go one digit to the right of the decimal. Now looking at Eleven we know we have 1 ten which needs to go two digits to the right of the decimal and 1 unit which needs to go one digit to the left of the decimal. Two tenths tell us that we must go one digit to the right of the decimal. Finally, we are adding the two numbers. Knowing the position of each number we then get 46.1 + 11.2

Numbers stated as 'units', 'tens', 'hundreds' and 'thousands' are listed to the left of a decimal while numbers listed as 'tenths', 'hundredths' and 'thousandths' are listed to the right of a decimal. One hundred lets us know the number goes three digits to the left of the decimal or 100. Three tenths lets us know that the number goes one digit to the right of the decimal or .3

Seventy-three tells us we have 7 tens that will go two digits to the left of a decimal and 3 units that will go one digit to the left of a decimal. We also have three thousandths that tell us the number must go three digits to the right of the decimal. Next the number thirteen tells us we have one ten that will go two digits to the left of the decimal and 3 units that will go one digit to the left of the decimal. The two tenths tell us the number will go one digit to the right of the decimal. With the number eighty we know we have 8 tens which will go two digits to the left of the decimal and 0 units will go one digit to the left of the decimal. The 8 hundredths will go two digits to the right of the decimal. We must then take note that this problem has us doing addition and subtraction. Knowing the position of each number we then get 73.003 + 13.2 - 80.08

Three tells us we have 3 units and must go one digit to the left of the decimal. The 8 tenths must go one digit to the right of the decimal. The number five tells us we have 5 units and the number will go one digit to the left of the decimal. The 4 tenths will then go one digit to the right of the decimal. Our final number is twenty-nine which tells us we have 2 tens that will go two digits to the left of the decimal, 9 units that will go one digit to the left of the decimal and one hundredth that will need to go two digits to the right of the decimal. Next we need to note that all numbers are being added. Knowing the position of each number we then get 3/8 + 5/4 + 29.01
