-7.1-(-8.3)= 1.2**ok**

multiply

(7.6)(1)(-6)

= -45.6**OK**

divid

90/18 = 5**OK**

find the reciprocal of 1/3 (9-4= 5/3**A parenthesis is missing and I don't understand the problem. If it is**

(9-4)/3 = 5/3 and the reciprocal is 3/5. If it is 1/[3*(9-4)] = 1/15 and the reciprocal is 15.

90/18 = 5**I might have said the answer was 5.0 since there are two significant figures each in 90 and 18 so you are allowed 2 s.f. in the answer. I don't know if you have had anything about s.f. or not.**
