Answer:

a) x= 42 , b) x=(16)/(9) , c) x=60

Step-by-step explanation:

a)

  1. Divide 48 by 8    -   48 / 8 = 6
  2. Multiply 6 by 7   -    6 x 7 = 42
  3. You get x = 42

b)

  1. Flip (9)/(2)…(i.e. reciprocal)
  2. Multiply 8 and 2 - 8 x 2 = 16
  3. You get x = (16)/(9)

c)

  1. Divide 80 by 4 - 80 / 4 = 20
  2. Multiply 20 by 3 - 20 x 3 = 60
  3. You get x = 60
