You have =
To cross multiply we multiply the denominators (5/4) and (3/2) to the opposite sides (creating a cross) like so:
---------
step 1: take (5/4) to the right by multiplying (5/4) on both sides
=
(5/4)/(5/4) on the left cancel each other out because it equals 1
---------
step 2: take (3/2) to the left by multiplying (3/2) on both sides
(3/2)/(3/2) on the right cancel each other out because it equals 1
---------
step 3: simplify the left by multiplying numerators and denominators (top and bottom)
---------
step 4: solve for y by multiplying by 4 and dividing by 5 on both sides(also known as multiplying by the reciprocal fraction (4/5))
