1)There 40 pupils in a class.

There is chart so i counted the number of boys and the number of girls
Boys-24
Girls- 16
what is the ratio of girls to boys in the class? Answer in simplest form
My answer- 16:24
4:6 (ratio in simplest form)
is this correct?

2) This questioned I am confused on
the ratio of adults to children visiting a park is 3:5
one day 1740 adults go to the park
how many children go to the park on that day?

please help

many thanks

1) you have a good start - but put the boys 1st -- 24 to 16 then reduce until you get 3 to 2. One way to check would be out of 5 students 3 are boys and 2 are girls 40 students divided by our 5 is 8 sub groups and 8 times our 3 boys is a total of 2 boys and 2 girls times 8 is 1 so the 3 to 2 checks out.

2) One way to solve this would be to find out the total crowd. adults are 3 out of 8 which is .375 %. to find the total group take the adults 1740 and divide by .375 % and you get 4640. Then take the 4640 and subtract the adults 1740 and you get 2900 children.

1) Yes, your answer is correct. To simplify the ratio 16:24, you can divide both numbers by their greatest common factor, which is 8. So the simplified ratio is 4:6.

2) To find the number of children who went to the park on that day, you can set up a proportion using the ratio of adults to children.

The ratio of adults to children is 3:5, which means for every 3 adults, there are 5 children.

Let's call the number of children who went to the park on that day "x".

So, we can set up the proportion:

3 adults / 5 children = 1740 adults / x children

To solve for x, we can cross-multiply:

3x = 1740 * 5

3x = 8700

Now, divide both sides of the equation by 3:

x = 8700 / 3

x = 2900

Therefore, on that day, 2900 children went to the park.

1) To find the ratio of girls to boys in the class, you need to simplify the ratio.

In this case, the number of girls is 16 and the number of boys is 24. To simplify the ratio, you need to find the greatest common divisor (GCD) of the two numbers and divide both numbers by the GCD.

The GCD of 16 and 24 is 8. Divide 16 by 8 to get 2, and divide 24 by 8 to get 3. So, the simplified ratio of girls to boys is 2:3.

Therefore, your answer of 4:6 is not correct. The correct and simplified ratio is 2:3.

2) To determine the number of children visiting the park on that day, you can use the given ratio of adults to children, which is 3:5.

Given that there were 1740 adults, you can set up a proportion using the ratio.

3/5 = 1740/x

Cross-multiplying, you get:

3x = 5 * 1740

Now, divide both sides of the equation by 3 to solve for x:

x = (5 * 1740) / 3

x ≈ 2900

Therefore, approximately 2900 children went to the park on that day.
