if a/4 = 2/3, then (a - 4)/4 would equal
a) -2/3
b) -1/3
c) 0
d) 1/3

The equation
a/4 = 2/3
do cross multiplication
8 = 3a
a = 8/3

Performing the expression.
= (a - 4) / 4
= (8/3 - 4) / 4
= (8-12 / 3)/4
= -4/3 / 4
= -1 / 3

So the answer is letter b.

Iknow one of the answers is a and maybe b but not 100% sure about b
