Answer 9

now what do i do with it??

Answer 10

8+8=16+8=24+8=32+8=40
5+5=10+5=15+5=20+5=25+5=30+5=40
they meet at 40 or 8*5

that is now our new denominator, but we have to change numerators so they are equivalent
-5/8 = -25/40 i multiplied both top and bottom by 5
-6/5 = -48/40 multiply top and bottom by 8

Answer 11

once you have the new fractions with same denominator just add the top numbers
-25 + -48 = -73
= -73/40

Answer 12

ohhh okk

Answer 13

that was right! ok last one!

Answer 14

if you have to just multiply the bottom numbers, that will always give you a common denominator

Answer 15

always look for 2 neg signs next to each other, they cancel each out
do this first

Answer 16
