Answer:

29. \frac{1}{3}

30. a) 32

b) Yes, the ratio will change 1 : 2.

Step-by-step explanation:

<em>Question 29.</em>

Given that:

Number of gold medals won by France = 11

Number of silver medals won by France = 9

Number of bronze medals won by France = 13

To find:

The ratio of gold medals won to the total number of medals won by France.

Solution:

First of all, we need to find the total number of medals won by France.

Total number of medals won = 11 + 9 + 13 = 33

The required ratio can be found as:

\dfrac{\text{Number of gold medals won}}{\text{Total number of medals won}}\\\Rightarrow \dfrac{11}{33}\\\Rightarrow \bold{\dfrac{1}{3}}

<em>Question 30:</em>

Number of girls = 20

Ratio of boys to Ratio of girls = 3 : 5

a. Total number of students in the class?

First of all, we need to find the number of boys in the class then we will add the value to the number of girls to get the answer.

Let the number of boys = x

As per the ratio, we can write:

\dfrac{3}{5 } = \dfrac{x}{20}\\\Rightarrow x = 12

Total number of students = 20 + 12 = <em>32</em>

b. Four number of boys and four girls are moved to other class.

Number of boys left = 12 - 4 = 8

Number of girls left = 20 - 4 = 16

New ratio = 8 : 16 = <em>1 : 2</em>

Therefore, the ratio got changed to <em>1 : 2</em>.

DochEvi [55]

Answer:

6x = 42

Step-by-step explanation:

The formula to find the area of a rectangle is A = LxW. Since we have a value for the width, we simply need to find what to multiply to 6 to get 42.

Let x = length

6x = 42

We then divide both sides by 6 to find the value of x.

\dfrac{6x}{6}=\dfrac{42}{6}

x=7

So we know the length is 7.

To check the answer we substitute x with 7.

6(7)=42

42=42
