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

Explanation:

Let molecule = N and also denominator = D.

According to the very first statement,

N = (D x 5) + 4.

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

Let"s main point the 2nd equation by –2 and add itthe very 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 need to multiply both political parties by the denominator to remove the fraction.

Doing this yields

Then to settle the last step is to isolate the variable by splitting both sides by 12.Thus,

.
