Question

Tonya has a small picture with a length of 4 2\5 inches. She wants to enlarge the picture by a factor of 7 and frame it. what is the size now?

Answer 1

you'll need to multiply the length * the scale factor

so 4 and 2/5, times 7

there's 2 ways you could do this

1. convert 4 2/5 to an improper fraction, and multiply by 7
2. re-write 4 and 2/5 as (4 + 2/5) then multiply the whole thing by 7, applying the distributive property 7(4 + 2/5)
