Question

4. Which of the following is equivalent to 4/5 a) 5/4. b) 16/25 c) 16/ 20. d) 16/25 ​

Answer 1

16/20

Hello :)

Step-by-step explanation -

Our task is to find the equivalent fraction of 4/5.

Equivalent means equal, so we're looking for a fraction that is equal to 4/5.

Such a fraction is 16/20, this is why:

`\sf{\cfrac{4}{5}=\cfrac{4*4}{5*4}=\cfrac{16}{20}}`

Henceforth, C is the right answer.

Answer 2

Answer: c)
`(16)/(20)`

Explanation:

To find the equal fraction, you have to cross multiply both values, meaning we multiply the numbers diagonal from each other. So set the equation
`(4)/(5) =(16)/(20)`.

So we would multiply 4 & 20 and 5 & 16. If we multiply these, we would get 80=80, confirming our work.

To check your answer divide 4 & 5 and 16 & 20.

If you divide the pair of numbers you should get 0.8 for both, meaning the answers are equal.

Hope that helped.
