In Ms.Khans class,22 out of 25 students hand in their projects on time. What percent of the class hand in their projects on time
Nikitich [7]

88 % students of the class hand in their projects on time

<em><u>Solution:</u></em>

Given that, Ms.Khans class, 22 out of 25 students hand in their projects on time

Total number students = 25

Students hand in their projects on time = 22

<em><u>To find: percent of the class hand in their projects on time</u></em>

\text{ percent of class hand in time } = \frac{\text{Students hand in projects on time}}{\text{total students}} \times 100

Substituting the values, we get

\text{ percent of class hand in time } = \frac{22}{25} \times 100\\\\\text{ percent of class hand in time } = 0.88 \times 100\\\\\text{ percent of class hand in time } = 88

Thus 88 % students of the class hand in their projects on time

Jack has a cat that is 4 times as large as jill's cat. combined, both cats weigh 35 pounds. how much does jacks cat weigh ?
Sever21 [200]
If we say that the weight of Jill's cat is w, then we can say that the weight of Jack's cat is 4w.

We know that the combined weight is 35 pounds, so we can write this as

4w+w=35

Which simplifies to

5w=35

If we divide by 5, we are left with

w=7

So that gives us the weight of Jill's cat. If Jack's cat weighs 4 times as much, we can see that

4x7=28

Therefore, Jack's cat weighs 28 pounds :)
