Solve the following equation 2/3x+6=1/2x+1/4x
Vanyuwa [196]

Answer:

x= 72

Step-by-step explanation:

combine the Xs on one side and then make the denominators the same and solve

8/12X +6 = 3/4X

sub 6 on both sides

then sub 3/4 (aka. 9/12)

-1/12X= -6

multiply by reciprocal (the fraction flip-flopped)(-12) on both sides

and you get 72

monique has 3/4 of tissues. if she cuts half of those tissues how much did she cut? put the answer in a fraction and percentage(
skelet666 [1.2K]

The required fraction of the tissue she cut is 3 /8, and the percentage is 37.5%.

Given that,
Monique has 3/4 of tissues. she cuts half of those tissues

<h3>What is the fraction?</h3>

Fraction is defined as the number of compositions that constitute the Whole.

Here,
Let the number of tissue be x,
She has 3 / 4 of the tissues = 3 / 4 x
she cuts half of those tissues = 1 / 2 * 3 / 4 * x
                                             = 3/8x or 37.5% of x

Thus, the required fraction of the tissue she cut is 3 /8, and the percentage is 37.5%.
