Write the expression in fewer terms: 3•15+4•15-5•15

By fewer terms, I assume it means you can reduce each multiplication of 2 terms down to 1. Therefore I would say:

45+60-75.

otherwise, maybe it means give the full 1 answer of:

30.

I used PEMDAS. You simplify the multiplication terms first, then you do the addition and subtraction.

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

if i put something wrong your not gonna like it so rather not say nothing.
