It is the third one because it equals the same as 8 times 54 . I hope this helped
How Much did the dinner cost? 12 divided by 3 = 4 So each person would pay 4$ for the tip.
First make common denominators.
Multiply 6 to numerator and denominator of 7/2
7/2(6/6) = 42/12
Add the two fractions together.
42/12 + 11/12 = 53/12
Change the improper fraction into mixed fraction, and simplify if need be.
53/12 = 4 5/12
4 5/12 feet is your answer
hope this helps
