Answer 1

Answer:

Maybe it will be helpful for you my dear :)

Step-by-step explanation:

The given ratio is 8:11. And you want it to become 4:5.

So add x to both digits as

(8+x):(11+x) = 4:5, or

4(11+x) = 5(8+x), or

44+4x = 40+5x, or

5x-4x = 44–40, or

x = 4.

Add 4 to both numerator and denominator of the fraction (8/11) to get a fraction of (4/5).

Answer 2

4

Step-by-step explanation:

so add x to both digits as

(8+x) : (11+x) = 4:5 or

4(11+x) = 5(8+x) or

44+4x = 40+5x, or

5x - 4x = 44 - 40, or

x = 4

Add 4 to both numerator and denominator of the fraction (8/11) to get a fraction of (4/5)
