Question

A pattern has 10 blue triangles to every 70 yellow triangles. What is
the ratio of blue triangles to all triangles?

Answer 1

To find the ratio of blue triangles to all triangles, first we need to determine the total number of triangles by adding the blue and yellow triangles together.

We have:
- 10 blue triangles
- 70 yellow triangles

Now, we calculate the total number of triangles:
\[
\text{Total triangles} = \text{Blue triangles} + \text{Yellow triangles} = 10 + 70 = 80
\]

Next, we can find the ratio of blue triangles to all triangles:
\[
\text{Ratio of blue triangles to all triangles} = \frac{\text{Blue triangles}}{\text{Total triangles}} = \frac{10}{80}
\]

We can simplify this ratio:
\[
\frac{10}{80} = \frac{1}{8}
\]

So, the ratio of blue triangles to all triangles is \(\frac{1}{8}\).
