Question

A pattern has 4 blue triangles to every 12 yellow triangles.what is the ratio of blue triangles to all triangles?

Answer 1

Answer:

A pattern has 4 blue triangles and 12 yellow triangles.

Total number of triangles 4+12=16

The ratio of blue is

r=\frac{\text{Number of blue triangles}}{\text{Total number of triangles}}

r=\frac{4}{16}

r=\frac{1}{4}

Therefore, the ratio of blue is 1 : 4.

Answer 2

Given :

• A pattern has 4 blue triangles to every 12 yellow triangles.

To find :

• The ratio of blue triangles =?

Step-by-step explanation :

A pattern has 4 blue triangles and 12 yellow triangles. [Given]

Now, We have to find the total number of triangles,

So,

Total number of triangles = Number of blue triangles + Number of yellow triangles.

Substituting the values, we get,

= 4 + 12

= 16

Therefore, Total number of triangles = 16.

Now,

The ratio of blue,

Ratio = Number of blue triangles / Total number of triangles.

Substituting the values in the above formula, we get,

Ratio = 4 / 16

Ratio = 1 / 4

Therefore, the ratio of blue triangles = 1 : 4.
