Question

Francine cooks vegetable stir-fry 15 days in 4 weeks and chicken stir-fry 6 days in 4 weeks. What percent of the days does Francince cook stir-fry?

Answer 1

It would be 29 or if you multiply it would be different

Answer 2

One week contains 7 days :

4x7 = 28
so 15/28

then

6/28 for chicken

now gather it:

6/28 + 15/28 = 21/28

21/28 = 0.75
