The numerator of a portion is the amount of 4 and also 5 times the denominator. If you division the portion by 2, the molecule is 3 time the denominator. Uncover the streamlined version of the fraction.


Explanation:

Let molecule = N and also denominator = D.

According come the very first statement, 

N = (D x 5) + 4.

According come the 2nd statement, N / 2 = 3 * D. 

Let"s multiply the 2nd equation through –2 and include itthe first equation:

–N = –6D

+

=

–6D + (D x 5) + 4 = 0

–1D + 4 = 0

D = 4

Thus, N = 24.

Therefore, N/D = 24/4 = 6.


Explanation:

To deal with this equation we have to multiply both sides by the denominator to get rid of the fraction.

Doing this yields

*
 

Then to solve the last step is to isolate the change by separating both sides by 12.Thus,
