Question

What's the answer to number 25?

Answer 1

Find the difference 

5/6-3/4 (you have to get the same denominators by multiply the individual fractions)

(5/6)*2 and (3/4)*3 to get a denominator of 12

10/12-9/12 (subtract numerators, leave denominator)
=1/12 which is the answer

5/6-3/4 =(20-18)/24 = 2/24
