Answer:
3 3/5 + 1 1/4 = <u>4 17/20</u>
7/8 + 1/12 =<u> 23/24</u>
8/9 - 2/5 = <u>22/45</u>
5 1/4 - 2 2/3 = <u>2 7/12</u>
Step-by-step explanation:
3 3/5 + 1 1/4
First convert into improper fractions
= 18/5 + 5/4
Now find the common denominator
72/20 + 25/20 = 
97/20
Now simplify
4 17/20
<u>Next problem:</u>
7/8 + 1/12
find the common denominator
21/24 + 2/24 = 
23/24
<u>Next problem:</u>
8/9 - 2/5
find the common denominator
40/45 - 18/45 = 
22/45
<u>Next problem:</u>
5 1/4 - 2 2/3
First convert into improper fractions
21/4 - 8/3 
find the common denominator
63/12 - 32/12 = 
31/12
Now simplify
2 7/12

First, you set up the equation which would be 5y-8=3y-4.
                                                                             -3y       -3y
                                                                               2y-8= -4
                                                                                 +8    +8
                                                                                  2y=4
                                                                               divide by 2    
                                                                                   y=2
