Question

Insert the required factor in the parentheses. 

Do NOT use spaces in your answers. 

a) 9x+3/4=3/4(answer)

b) 3/4 X+1/2=1/4(answer)

Answer 1

(a) 3/4 is factored out, so 9 divided by 3/4 = 9 * 4/3 = 12

3/4(12x + 1)

(b) 1/4 is factored out, so 1/2 divided by 1/4 = 1/2 * 4/1 = 2

1/4(3x + 2)
