I'm stuck on another question 5 4/5 + (-3 2/7)

So that would be the same thing as 5 4/5 - 3 2/7

Put them in mixed fractions to become 29/5 - 23/7

Multiply one side by 7 and one side by 5 to get the same denominator

203/35 - 115/35

Now subtract the numerators to get

88/35

Or if they want it inixed numbers then 2 18/35

54/5 - 32 / 7

= (378 - 160) / 35

=218/35
