Do the ratios 1/2 and 10/20 form a proportion?

Question: Do the ratios 1/2 and 10/20 form a proportion?
(1) Yes
(2) No

Solution:

Remember :
Two equivalent ratios form a proportion.
Equivalent ratios have the same value.

To determine whether the two ratios 1/2 and 10/20 form a proportion, you can compare them using a common denominator.
The denominators are 2 and 20. You can use 20 as the common denominator since 20 is a multiple of 2.
Write 1/2 with a denominator of 20.
1/2 = 110/220 = 10/20
So, 1/2 and 10/20 are equal.
This means that the ratios 1/2 and 10/20 form a proportion.
Then the answer is Yes.
