Write the multiplier or divisor for each pair of equivalent fractions 1/4 = 7/28

The equivalent fraction is 1/4 = 7/28
the multiplier or divisor for the equation is 7
if we divide to each pair of equation with 7 equation we get the same answer 
like when we 7 is divisor in 1 / 4 we get the answer 1/ 28
and with 7/ 28, we also get the answer 1 / 28
and the when we multiply 7 with 1/4 we get the answer 7/4 and with 7 /28, also the answer is 7/4.
