Question

What fraction of students wears black or white shoes? 1/2 wear black shoes and 2/5 wear white shoes

Answer 1

Explanation:

You want to add these two fraction together so they need to have the same denominator. Find the common denominator by multiplying both denominators

2x5=10

then convert the fractions

(1/2)x5=5/10

(2/5)x2=4/10

now you can add them

(5/10)+(4/10)=9/10

so 9/10 students wear black or white shoes
