Question

An illustration shows insects, all the same size, shaded in two patterns. The first group of shaded insects is shown in two rows, with each row containing 5 insects. Next to these are two insects with a different shading than the first group.
Identify the ratio of plain blue bugs to the total number of bugs.

Answer 1

To find the ratio of plain blue bugs to the total number of bugs, let's break down the information provided:

1. The first group of insects consists of 2 rows of 5 insects each:
- Total from the first group = 2 rows x 5 insects/row = 10 insects.

2. Next to these, there are 2 insects with a different shading.
- Total from the second group = 2 insects.

Now, we can calculate the total number of insects:

- Total number of bugs = Insects from the first group + Insects from the second group = 10 + 2 = 12 insects.

If we assume that all the bugs in the first group are plain blue, they make up the total number of plain blue bugs.

Now, we can identify the ratio of plain blue bugs to the total number of bugs:

- Ratio of plain blue bugs = Number of plain blue bugs : Total number of bugs = 10 : 12.

To simplify this ratio, we can divide both numbers by 2:

- 10 ÷ 2 = 5
- 12 ÷ 2 = 6

Therefore, the ratio of plain blue bugs to the total number of bugs is:

**5 : 6.**
