There are 12 total siblings in a family. There are 4 sisters, and the rest are brothers. What is the ratio of sisters to brothers?

Answer 1

To find the ratio of sisters to brothers, we first need to determine the number of brothers in the family.

Given that there are a total of 12 siblings and 4 of them are sisters, we can find the number of brothers by subtracting the number of sisters from the total:

$$\text{Number of brothers}=\text{Total siblings}-\text{Number of sisters}=12-4=8$$

Now we have 4 sisters and 8 brothers. The ratio of sisters to brothers can be expressed as:

$$\text{Ratio of sisters to brothers}=\frac{\text{Number of sisters}}{\text{Number of brothers}}=\frac{4}{8}$$

To simplify this ratio, we can divide both numerator and denominator by their greatest common divisor, which is 4:

$$\frac{4÷4}{8÷4}=\frac{1}{2}$$

Therefore, the ratio of sisters to brothers is:

$$\boxed{{\displaystyle 1:2}}$$
