    1. 39 = 1 3/10b

    ⇒ 39 = 13/10b

    ⇒ 39 / (13/10) = b

    ⇒ 30 = b

    2. 2/5g = 3/5

    ⇒ g = 3/5 / (2/5)

    ⇒ g = 3/2

    ⇒ g = 1 1/2

    Final answer:

    1. b = 30

    2. g = 1 1/2

    1. the answer is b = 30 ... you first simply both sides of the equation then flip it then multiply both sides by 10/13

    2. the answer is g = 3/2 ... multiply both sides by 5/2
