What fraction of the shape is shaded?

• 1/4

• 1/3

• 1/2

• 1

Answer explanation

I hope you chose 1/4 as your answer but many students make the mistake of choosing 1/3 because they count the unshaded pieces as the whole/denominator instead of ALL the pieces like they should.

If you made that mistake, it's okay, just learn from it and count ALL the pieces as your denominator next time.

• R

• S

• T

• U

Answer explanation

I hope you chose S but if you didn't, did you choose R? Many students count 3 lines and choose R instead of counting 3 spaces or parts which would get you to the right answer of S.

Remember, when you count lines instead of spaces/parts, you will get the wrong answer every time.

Fractions are about PARTS.

What fraction is green?

• 1/4

• 1/2

• 2/3

• 2/3

Answer explanation

2/4 is the fraction shown but 2/4 was not an answer choice.

We can see half the pieces are shaded and half are unshaded.

2 is half of the total 4, right?

Therefore, since 2/4 wasn't an answer choice, we can choose 1/2 as our answer.

2/4 is equivalent or equal to 1/2.
