how to turn 1/2 into 1/8 im counfused how to my teacher never explained

Answer 1

Maybe the teacher was trying to explain how to change halves into eighths

1/2 = 4/8

1/2 = x/8 solve for x

cross multiply

2x = 8

divide by 2

x = 8/2 = 4

1/2 = 4/8

if you multiply both numerator and denominator by the same number you get an equal fraction

(1x4)/(2x4) = 4/8

You're multiplying by 1, as 4/4 = 1

1/2 x 1 = 1/2

1/2 x 4/4 = 4/8

1/2 = 4/8
