Question

By what number should the sum of 4/3 and -9/10 be multiplied to get -1/12 as the product

Answer 1

Step-by-step explanation:

4/3+(-9/10)

4/3-9/10

40-27/30

13/30

x(13/30)=-1/12

13x/30=-1/12

13x(12)=-30

13x =-30/12

13x=-5/2

x=(-5/2)/13

x=-5/2×1/13

x=-5/26

Answer 2

Answer:

-5/26

Step-by-step explanation:

4/3 + (-9/10)

4×10/3×10 + (-9×3/10×3)

40 + (-27)/30

13/30

let the number be x

x × 13/30 = -1/12

13x/30 = -1/12

13x × 12 = -30

156x = -30

x = -30/156

x = -5/26
