Question

Express the ratio below in its simplest form. 5:2.5

Answer 1

Answer:

5 : 2.5 = 2 : 1

Step-by-step explanation:

Change values to whole numbers.

Convert any decimal numbers to integers by multiplying both sides by 101 = 10 to eliminate all, 1, decimal places.

We then have:

5 : 2.5 = 50 : 25

Try to reduce the ratio further with the greatest common factor (GCF).

The GCF of 50 and 25 is 25

Divide both terms by the GCF, 25:

50 ÷ 25 = 2

25 ÷ 25 = 1

The ratio 50 : 25 can be reduced to lowest terms by dividing both terms by the GCF = 25 :

50 : 25 = 2 : 1

Therefore:

5 : 2.5 = 2 : 1

Answer 2
