Someone please help me, it’s for my math homework! :)

Evaluate the following expression:42/12 - 85/25 + 117/30

Answer 1

4

Explanation:

Let's first simplify all terms, then convert them to /10:

42/12 = 7/2 = 35/10

85/25 = 17/5 = 34/10

117/30 = 39/10

Then the final addition is:

(35-34+39)/10 = 40/10 = 4
