Question

Lorenzo drew 3 triangles, 4 rectangles, and 7 arrows in a set of 20 shapes. The only other type of shape in the set is a circle. What fraction represents the part of the set that is circles?
3/20
4/20
6/20
7/20

Answer 1

Answer:

$\large\boxed{6/20}$

Step-by-step explanation:

In this question, we're trying to find how many circles are there and represent it as a fraction.

We know that he drew:

• 3 triangles
• 4 rectangles
• 7 arrows
• Set of 20 shapes

We need to find how many circles are there.

3 tiangles + 4 rectangles + 7 arrows = 14 shapes

We know that there is suppose to be 20 shapes, this means that the remaining amount would be circles (6 circles)

We now know that there are 6 circles and 20 shapes in total.

This means that the fraction that would represent circles is 6/20

I hope this helped you out.

Good luck on your academics.

Have a fantastic day!

Answer 2

Answer:

6/20

Step-by-step explanation:

Count up how many shapes he knows

3 triangles+ 4 rectangles + 7 arrows = 14

He has a total of 20

20 -14 = 6

That means he must have 6 circles

The fraction is circles/total  = 6/20
