Ok

D. 21 to 140

To determine which ratio is equivalent to 3/20, we can simplify the fraction 3/20.

To do this, we can find the greatest common divisor (GCD) of the numerator (3) and denominator (20). In this case, the GCD of 3 and 20 is 1.

Then, we can divide both the numerator and denominator by the GCD (1) to simplify the fraction.

So, 3/20 simplifies to 3/20, meaning the ratio itself remains unchanged.

Now, let's check the options:

a) 5 to 100
This ratio can be simplified as 1/20, which is not equivalent to 3/20.

b) 100 to 5
This ratio can be simplified as 20/1, which is not equivalent to 3/20.

c) 140 to 21
This ratio can be simplified as 20/3, which is not equivalent to 3/20.

d) 21 to 140
This ratio can be simplified as 3/20, which is equivalent to the given fraction.

Therefore, your selection of d) 21 to 140 as the ratio equivalent to 3/20 is correct.
