Answer:
The ratios in the simplest form is 5:3
Step-by-step explanation:
Given that:
2.5m to 150cm
We have to express these ratios in simplest form but we will convert the quantities into same unit first.
Therefore,
Converting meters into centimeters
1 meter = 100 cm
2.5 m = 100*2.5 = 250 cm
Ratio form;
250 cm : 150 cm
As both the number are multiples of 50,
Hence,
The ratios in the simplest form is 5:3
