Answer:
The helmet weighs 4 7/24 pounds more than the football.
Step-by-step explanation:
Since we are trying to figure how much more something weighs than the other, it would be necessary to subtract.
First, I decided to find common factors in the two fractions, which was 24. I used that as my denominator. 7/8 translates to 21/24 and the 1/6 in 5 1/6 translates to 4/24.
Using these new equivalent values, the equation turns into 5 4/24 - 21/24.
Solving that equation gives you 4 7/24, hence my answer.
Hope this helps.
