c...but you worte is wrong, numerator on right side with denominator on the left side, numerator on left side with numerator on right side
it is like this:
2/5 2 is the numerator and 5 is the denominator
3/6 3 is the numerator and 6 is the denominator
so you cross multiply = 2 multiply by six and 3 multiply by 5
answer= 12/15 divide by 3 (simplify it) answer will be 4/5

c.
Example: 1/2x = 2/3
Multiply : the numerator on left by denominator on right (1X3)
Then the numerator on the right by denominator on left (2x2)
3=4x
x = 3/4
