jackie has 168.8 feet of ribbon. She plans to cut the ribbon into 80 equal pieces to make bows for a craft fair. To find the length of each piece of ribbon, Jackie must find the quotient of 168.8/80.

Question

i really need help lmao

Answer 1

168.8/80 is the same as 16.88/8 (dividing top and bottom by 10). It’s easier to divide by 8 then to divide by 80. First divide 16 by 8 to get 2 followed by the decimal point. Now we can divide 88 by 8 to get 11. The decimal point comes in between: 2.11 feet. But what is 0.11 of a foot in inches? We find out by multiplying by 12 to get 1.32 inches (note that the number of decimal places in the product is 2, the same number as in 0.11). So the length of one piece of ribbon is 2ft 1.32in.
