Rewrite a as an improper fraction:

2 3/4 = 11/4

Now you have 11/4 x 4/5

Multiply the two top numbers together and the two bottom numbers together.

11x4 / 4x5 = 44/20 now rewrite as 2 4/20 which can simplify to 2 1/5

Is the ratio 3:4 the same as 4:5

Georgia [21]

Answer:

No the ratio 3:4 is not equal to 4:5

Step-by-step explanation:

3:4 = 3/4 and 4:5 = 4/5

3/4 is equal to 0.75 and 4/5 is equal to 0.8

0.75 $\neq$ 0.8

therefore, 3:4 $\neq$ 4:5

Hope this helps!
