A fraction is a number for part of a whole.

**What fraction of each figure is shaded?**

Question 1.

a.

b.

Answer: The shaded area in a fraction is \(\frac{3}{4}\).

Explanation: Given the square figure,

Now, we will write the shaded region values in fractions.

The given squares have 4 square parts. In this, three of the squares are shaded.

So, the shaded set value in fractions is \(\frac{3}{4}\).

c.

Answer: The shaded area in a fraction is \(\frac{4}{5}\).

Explanation: Given the rectangle figure,

Now, we will write the shaded region values in fractions.

The given rectangle has 5 rectangle parts. In this, four of the rectangles are shaded.

So, the shaded set value in fractions is \(\frac{4}{5}\).

Question 2.

a.

Answer: The shaded area in a fraction is \(\frac{1}{10}\).

Explanation: Given the Pentagon figure,

Now, we will write the shaded region values in fractions.

The given pentagon is 10 parts. In this, one of the parts is shaded.

So, the shaded set value in fractions is \(\frac{1}{10}\).

b.

Answer: The shaded set area in a fraction is \(\frac{3}{8}\).

Explanation: Given the circle figure,

Now, we will write the shaded region values in fractions.

The given circle has 8 parts. In this, 3 of the parts are shaded.

So, the shaded set value in fractions is \(\frac{3}{8}\).

c.

Answer: The shaded set area in a fraction is \(\frac{1}{2}\).

Explanation: Given the square figure,

Now, we will write the shaded region values in fractions.

The given square has 2 parts. In this, one of the parts is shaded.

So, the shaded set value in fractions is \(\frac{1}{2}\).

Question 3.

a.

Answer: The shaded set area in a fraction is \(\frac{2}{3}\).

Explanation: Given the circle figure,

Now, we will write the shaded region values in fractions.

The given circle has 3 parts. In this, 2 of the parts are shaded.

So, the shaded set value in fractions is \(\frac{2}{3}\).
