( 3 5/6 +а) - 2 1/6 =58 6/13 - (b+ 9/13) = 4 2/13

Question

( 3 5/6 +а) - 2 1/6 =5


8 6/13 - (b+ 9/13) = 4 2/13

Answer 1

(3 5/6+a)-2 1/6=5
3 5/6+a=5+2 1/6
3 5/6+a=7 1/6
a=7 1/6-3 5/6=6 7/6-3 5/6=3 2/6=3 1/3

2)8 6/13-(b+9/13)=4 2/13
b+9/13=8 6/13-4 2/13
b+9/13=4 4/13
b=4 4/13-9/13=3 17/13-9/13=3 8/13
