These are just multiplications.  For percents we have to move the decimal point two places. I assume calculators are OK.

2.

19.6% of 244 = .196(244) = 47.824

3.

20% of 75 = .2 (75) = 75/5 = 15

Didn't need a calculator for that one.

<em><u>Fractions</u></em><em><u> are integers that have both a numerator and a denominator. </u></em>They are represented as;  \frac{x}{y}

Where:

<em>x = Numerator</em>

<em>y = Denominator.</em>

<em />

To solve the above question, we would be applying the operations of the addition of fractions.

It will take both of them  27\frac{3}{11}  hours if they worked together.

From the question,

Nyesha takes 50 hours a week to render services to her customers.

Shantese takes 60 hours a week to do the same amount of work.

Let us represent the number of hours it will take them both to decorate the room working together as "T"

Hence,

1/T = 1/50 + 1/60

Lowest Common Denominator for (50, 60 ) = 300

Hence,

1/T = 6 + 5 / 300

1/T = 11/300

Find the reciprocal of both sides

T = 300/11 hours

T = 27\frac{3}{11} <u>hours</u>

Therefore, it will take them both of them 27\frac{3}{11} hours in they both work together.

zhannawk [14.2K]
Tammy's recipe makes a sweeter fruit punch. This is because 3/4 (Kim's recipe) equals 18/24 (Tammy's recipe) and 5/6 equals 20/24 and since 20/24 is the bigger ratio, Tammy's recipe will make a sweeter fruit punch. I hope this helps. (:
