Question

My daughter needs help with homework.

Answer 1

Just find the a common denominator between the two fractions and then add across 

For example on the first one i'm going to turn each fraction into an improper fraction by multiplying the whole number by the denominator then adding that number to the numerator 

2 1/8 = 17/8
4 2/3 = 14/3

Then multiply the denominators together to get 24 - this is the common denominator (24)

Figuring out the numerator is more complex - figure out what number needs to be multiplied to the original denominator that makes it 24 - then multiply that to the numerator. Add the two products and the answer should be 163/24.

This could be dead wrong because the number next to the fraction could be multiplying in - in that case the answer is 35/12 and has a completely different set of steps.
