Question

8/15 + what is equal to 7/12

Answer 1

Answer:

8/15 + 1/20 = 7/12

Step-by-step explanation:

Let 8/15 + a = 7/12

Therefore a = 7/12-8/15

LCM = 60

ie (7 x 5)/(12 x 5) - (8x4)/(15 x 4) = a

ie 35/60 - 32/60 = a

ie 3/60 = a

Therefore a = 3/60 = 1/20

Answer 2

Answer:

8/15 +x= 7/12

=)8+15x= 7x/12

=)12(8+15x)=7x

=)96+180x=7x

=)96=172x

=)x=4/43
