Question

Compare the ratios 4:5 and 16:20.

Answer 1

Answer:

They are equal

Step-by-step explanation:

When comparing ratios, we simply want to find out if the numbers are greater than, less than, or equal to each other. We have 4:5 and 16:20.

To find out the comparison;

Step 1: We find the LCM of the denominators ie 5 and 20, which is 20

Step 2: We divide the LCM by both sides, like this: 20÷5=4 and 20÷20=1.

Step 3: Now, multiply each ratio by the result of its individual denominator division ie

$\frac{4 \times 4}{5 \times 4} \: and \: \frac{16 \times 1}{20 \times 1} = \frac{16}{20} \: and \: \frac{16}{20}$

Step 4: Convert back to ratio form, we have: 16:20 and 16:20

From the above ratios, we have found out that 4:5 and 16:20 are equal when compared.

I hope this helps.
