35 girls and boys went walking. The ratio is 5 girls to every 2 boys. How many boys are there?

Answers

Answer 1
Answer:

Set up a proportion:

In a sample of 5:2, you have 7 kids in all.

So the the ratio of boys to kids in a sample of 7 is 2:7.

So set up a proportion:

(2)/(7) = (X)/(35)

7x =70

X = 10

Therefore, 10 of the boys went walking.
Answer 2
Answer: 5x-\ girls\n\n2x-\ boys\n\n5x+2x=35\n\n7x=35\ \ \ | divide\ by\ 7\n\nx=5\n\nThere\ are\ 10\ boys.

What percent is 40 % of 120 % of x?

Answers

The required percent  40% of 120% of x is equal to 0.48 times x.

What are percentages?

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

To find 40% of 120% of x, we can first find 120% of x, and then find 40% of that result.

120% of x can be found by multiplying x by 1.2:

120% of x = 1.2 * x

Next, to find 40% of the result, we multiply by 0.4:

40% of (120% of x) = 0.4 * (1.2 * x)

So the final answer is:

40% of 120% of x = 0.4 * (1.2 * x) = 0.48x

This means that 40% of 120% of x is equal to 0.48 times x.
