1.Fund the sum (g+6/g-1)+(-7/g-1)

2.Find the difference (q+4/q-1)-(5/q-1)

3.Find the sum (3/h-6)+(4/h+1)

Since your denominators are the same, simply add the numerators to get:

2.Find the difference (q+4/q-1)-(5/q-1)

Again, same thing. Denominator is the same, so combine like terms for the numerator and get:

3.Find the sum (3/h-6)+(4/h+1)

Okay, on this one the denominators are different. To make them the same, multiply them together. Also, you will want to multiply the numerator by the other denominator, here's what I mean.

Once you finish the mutliplication, you can factor things out:

Just make sure the denominators are always the same when adding or subtracting with fractions!

You're "not gona have time to study...." ? WHY???
Do you spend your homework time at MacDonald's comparing
tattoos and ear/nose/.../rings, tripping over pants with the
crotch down to below your knees ???
