The ratio of the number of white shapes to the number of black shapes is 5:11
The ratio of the number of white circles to the number of white squares is 3:7
The ratio of the number of black circles to the number of black squares is 3:8
Work out what fraction of all the shapes are circles.

the fractions of all the shapes are circles can be obtained would be computed as:  

Step-by-step explanation:

The fraction of the number of white shapes to the number of black shapes is 5/11.

Let us consider that there are:

As the fraction of the number of white circles to the number of white squares is 3:7

It means out of 10 total parts, 3/10 are white circles and 7/10 are white squares.

Calculating Number of white circles:

Calculating Number of white squares:

As the fraction of the number of black circles to the number of black squares is 3:8.

Calculating Number of black circles:

Calculating Number of black squares:

As

Therefore, the fractions of all the shapes are circles can be obtained would be computed as:
