(trom Unit 4, Lesson 11)
Dima020 [189]

Answer:

The number of kids NOT wearing socks in the gym = 20

Step-by-step explanation:

Here, the total number of kids in the gym = 80

Now, 75% of the kids are wearing socks.

Let us assume the number of kids wearing socks  = m

⇒ 75 % of 80 = m

Calculating the value of m ,we get:

\frac{75}{100}  \times 80 = m\\\implies  m = 60

⇒ 60 kids are wearing socks.

Kids not wearing socks = Total kids in gym - Kids wearing socks

= 80 - 60 = 20

Hence, the number of kids NOT wearing socks in the gym = 60.

Solve the proportion.<br><br> 8/7 = n/9
RoseWind [281]
\frac{8}{7} = \frac{n}{9}

Cross multiply the fractions:

7 \times n = 7n
8 \times 9 = 72

7n = 72

Divide both sides by 7 to get n by itself:

72 \div 7 = 10.28
n = 10.28

The value of n is 10.28.
