Answer:
17.5 or 17 1/2 its the same thing
Explanation:
first you make the 5 a fraction by putting a one under it
so it would be 7/2 ×5/1 then you multiply 7×5 is 35
and then 2 × 1 is 2 so the answer would be 35 /2 but that's not the simplified answer .
the next thing you do is divide 35 by 2 and get 17.5
hope this helps:)sorry if it doesnt
