Question

This table shows the ratio of the number of red beans to the total number of beans.

A 2-column table has 2 rows. Column 1 is labeled Total with entries 30, and 15. Column 2 is labeled Red with entries 20, and 10.

Which ratios are equivalent to 30:20? Check all that apply.
40:30
10:0
3:2





the answer is C and D

Answer 1

The ratio which is equivalent to 30:20 is option C, 3:2.

How to obtain real measurements from the ratio of two measurements?

Suppose the  real measurements were "a" and "b"

Then their ratio will be formed as

$\dfrac{a}{b} = \dfrac{p \times x}{q \times x} = \dfrac{p}{q}$

where is a common factor (not 1)? This shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly canceled from both the numerator and the denominator.

Thus, a = px, b = qx

We have given that a 2-column table has 2 rows. Column 1 is labeled

The Total with entries 30, and 15. Column 2 is labeled Red with entries 20, and 10.

Given ratio is 30:20

Or

3:2

Therefore, we can conclude that the ratio which is equivalent to 30:20 is option C, 3:2.
