Answer:

Number of CDs in Walter's collection = x = 36

Step-by-step explanation:

x denotes number of CDs in Walter's collection.

Also, the number of CDs in Brian's collection is 3 times the number in Walter's collection.

Number of CDs in Brian's collection =3x

Total number of CDs in both Walter's collection and Brian's collection = 144

x+3x=144\\4x=144\\x=\frac{144}{4}\\ x=36

So,

Number of CDs in Walter's collection = x = 36

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%.
