Which ratio is equivalent to 4 to 5?
algol [13]

Answer:

4 / 5 = 8 / 10

Step-by-step explanation:

4:5 is a ratio which can be rewritten as 4/5.

Any number that is multiplied by both the 4 and the 5 is an equivalent ratio to 4:5.

For example, if we multiply 2 by both sides, we have 8 to 10 which is equal to 4 to 5.
