In a school, 2/3 of students study a language. Of those who study a language, 2/5 study French. Find the Ratio of student who study French to students who do not study French. Give your answer in the simplest form.Must be in Ratio __ : __

Answers

The ratio of students who study French to students who don't is 4 : 11

Ratio shows the relationship that exists between two or more numbers. It displays the number of times a value is contained in another value

The fraction of students that study a language = 2/3

fraction of students that study French = (2)/(3) × (2)/(5) = (4)/(15)

Fraction of students that do not study French = 1 - (4)/(15) = (11)/(15)

The ratio ;(4)/(15) : (11)/(15)

(4)/(15) ÷ (11)/(15)

(4)/(15) × (15)/(11)

= 4 : 11

Answer: 4:11

Step-by-step explanation:

Given : Fraction of students study a language =(2)/(3)

Let x be the number of students in the school.

Then , No. of students study a language =(2)/(3)x

Fraction of students who study a language study French  =(2)/(5)

No. of of students who study a language study French  =(2)/(5)x

No. of students study French =(2)/(5)*(2x)/(3)=(4x)/(15)

Then, the number of students do not study French = x-(4x)/(15)=(15x-4x)/(15)=(11x)/(15)

Now, the ratio of student who study French to students who do not study French:-

((4x)/(15))/((11x)/(15))=(4)/(11)=4:11

Hence, the required answer =  4:11

Answers:

C, D, E

Step-by-step explanation:

A rational number is a integer. It is also a terminating or repeating decimal.

A rational number can be written as a fraction of two integers.

Answer A is not correct because it's decimal never ends. It is also not repeating. A cannot be written as a fraction.

Answer B is not correct because the square root is not a whole number, or a perfect square. The square root has a non-terminating and non-repeating decimal, just like A. B cannot be written as a fraction.

Answer C is rational because it has a terminating decimal.

D and E are integers, which also can be written as fractions.

Out of the options given, C, D, and E have rational numbers, while all others do not.

The answers are C, D, and E.
