Question

It’s takes 3/5 yard of ribbon to make a bow. How many bows could you make with 7 1/2 yards of ribbon?

Answer 1

`12(1)/(2)\ bows`

Explanation:

we know that

It’s takes 3/5 yard of ribbon to make a bow

using proportion

Find out how many bows could you make with 7 1/2 yards of ribbon

Remember that

`7(1)/(2)\ yd=(7*2+1)/(2)=(15)/(2)\ yd`

so

`((3/5))/(1)\ (yd)/(bow)=((15/2))/(x)\ (yd)/(bows)\\\\x=((15/2))/((3/5))\\\\x=(75)/(6)\ bows\\\\x=12.5\ bows`

Convert to mixed number

`12.5\ bows=12(1)/(2)\ bows`
