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

Answer:

$12\frac{1}{2}\ bows$

Step-by-step 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

$7\frac{1}{2}\ yd=\frac{7*2+1}{2}=\frac{15}{2}\ yd$

so

$\frac{(3/5)}{1}\ \frac{yd}{bow}=\frac{(15/2)}{x}\ \frac{yd}{bows}\\\\x=\frac{(15/2)}{(3/5)}\\\\x=\frac{75}{6}\ bows\\\\x=12.5\ bows$

Convert to mixed number

$12.5\ bows=12\frac{1}{2}\ bows$
