Questions and Answers
Q 1 - Convert $\mathbf {2 \frac{1}{5}}$ into a decimal.

Answer : A

Explanation

Step 1:

Converting the mixed number $2 \frac{1}{5}$ into an improper fraction, $2 \frac{1}{5} = \frac{11}{5}$.

Step 2:

We write an equivalent fraction of $\frac{11}{5}$ with a denominator 10.

$\frac{11}{5} = \frac{\left ( 11 \times 2 \right )}{\left ( 5 \times 2 \right )} = \frac{22}{10}$

Step 3:

Shifting the decimal one place to the left we get $\frac{22}{10} = 2.2$

Step 4:

So, $2 \frac{1}{5} = 2.2$

Q 2 - Convert $\mathbf {3 \frac{1}{2}}$ into a decimal.

Answer : B

Explanation

Step 1:

Converting the mixed number $3 \frac{1}{2}$ into an improper fraction, $3 \frac{1}{2} = \frac{7}{2}$.

Step 2:

We write an equivalent fraction of $\frac{7}{2}$ with a denominator 10.

$\frac{7}{2} = \frac{\left ( 7 \times 5 \right )}{\left ( 2 \times 5 \right )} = \frac{35}{10}$

Step 3:

Shifting the decimal one place to the left we get $\frac{35}{10} = 3.5$

Step 4:

So, $3 \frac{1}{2} = 3.5$

Q 3 - Convert $\mathbf {1 \frac{1}{4}}$ into a decimal.

Answer : C

Explanation

Step 1:

Converting the mixed number $1 \frac{1}{4}$ into an improper fraction, $1 \frac{1}{4} = \frac{5}{4}$.

Step 2:

We write an equivalent fraction of $\frac{5}{4}$ with a denominator 10.

$\frac{5}{4} = \frac{\left ( 5 \times 25 \right )}{\left ( 4 \times 25 \right )} = \frac{125}{100}$

Step 3:

Shifting the decimal one place to the left we get $\frac{125}{100} = 1.25$

Step 4:

So, $1 \frac{1}{4} = 1.25$

Q 4 - Convert $\mathbf {3 \frac{1}{5}}$ into a decimal.

Answer : D

Explanation

Step 1:

Converting the mixed number $3 \frac{1}{5}$ into an improper fraction, $3 \frac{1}{5} = \frac{16}{5}$.

Step 2:

We write an equivalent fraction of $\frac{16}{5}$ with a denominator 10.

$\frac{16}{5} = \frac{\left ( 16 \times 2 \right )}{\left ( 5 \times 2 \right )} = \frac{32}{10}$

Step 3:

Shifting the decimal one place to the left we get $\frac{32}{10} = 3.2$

Step 4:

So, $3 \frac{1}{5} = 3.2$

Q 5 - Convert $\mathbf {4 \frac{1}{2}}$ into a decimal.

Answer : C

Explanation

Step 1:

Converting the mixed number $4 \frac{1}{2}$ into an improper fraction, $4 \frac{1}{2} = \frac{9}{2}$.

Step 2:

We write an equivalent fraction of $\frac{9}{2}$ with a denominator 10.

$\frac{9}{2} = \frac{\left ( 9 \times 5 \right )}{\left ( 2 \times 5 \right )} = \frac{45}{10}$

Step 3:

Shifting the decimal one place to the left we get $\frac{45}{10} = 4.5$

Step 4:

So, $4 \frac{1}{2} = 4.5$

Q 6 - Convert $\mathbf {5 \frac{1}{5}}$ into a decimal.

Answer : B

Explanation

Step 1:

Converting the mixed number $5 \frac{1}{5}$ into an improper fraction, $5 \frac{1}{5} = \frac{26}{5}$.

Step 2:

We write an equivalent fraction of $\frac{26}{5}$ with a denominator 10.

$\frac{26}{5} = \frac{\left ( 26 \times 2 \right )}{\left ( 5 \times 2 \right )} = \frac{52}{10}$

Step 3:

Shifting the decimal one place to the left we get $\frac{52}{10} = 5.2$

Step 4:

So, $5 \frac{1}{5} = 5.2$

Q 7 - Convert $\mathbf {6 \frac{1}{2}}$ into a decimal.

Answer : D
