Questions and Answers

Answer : C

Explanation

Step 1:

Since denominators are same, adding the numerators

$\frac{6}{8}$ + $\frac{4}{8}$ = $\frac{(4+6)}{8}$ = $\frac{10}{8}$

Step 2:

Reducing to the lowest terms, $\frac{10}{8}$ = $\frac{5}{4}$

Step 3:

So, $\frac{4}{8}$ + $\frac{6}{8}$ = $\frac{5}{4}$

Q 2 - Subtract $\frac{7}{6}$$\frac{4}{6}$

Answer : A

Explanation

Step 1:

Since denominators are same, subtracting the numerators

$\frac{7}{6}$$\frac{4}{6}$ = $\frac{(7−4)}{6}$ = $\frac{3}{6}$

Step 2:

Reducing to the lowest terms, $\frac{3}{6}$ = $\frac{1}{2}$

Step 3:

So, $\frac{7}{6}$$\frac{4}{6}$ = $\frac{1}{2}$

Answer : D

Explanation

Step 1:

Since denominators are same, adding the numerators

$\frac{3}{4}$ + $\frac{7}{4}$ = $\frac{(3+7)}{4}$ = $\frac{10}{4}$

Step 2:

Reducing to the lowest terms, $\frac{10}{4}$ = $\frac{5}{2}$

Step 3:

So, $\frac{3}{4}$ + $\frac{7}{4}$ = $\frac{5}{2}$

Q 4 - Subtract $\frac{7}{9}$$\frac{4}{9}$

Answer : A

Explanation

Step 1:

Since denominators are same, subtracting the numerators

$\frac{7}{9}$$\frac{4}{9}$ = $\frac{(7−4)}{9}$ = $\frac{3}{9}$

Step 2:

Reducing to the lowest terms, $\frac{3}{9}$ = $\frac{1}{3}$

Step 3:

So, $\frac{7}{9}$$\frac{4}{9}$ = $\frac{1}{3}$

Q 5 - Subtract $\frac{10}{12}$$\frac{7}{12}$

Answer : B

Explanation

Step 1:

Since denominators are same, subtracting the numerators

$\frac{10}{12}$$\frac{7}{12}$ = $\frac{(10−7)}{12}$ = $\frac{3}{12}$

Step 2:

Reducing to the lowest terms, $\frac{3}{12}$ = $\frac{1}{4}$

Step 3:

So, $\frac{10}{12}$$\frac{7}{12}$ = $\frac{1}{4}$

Answer : C

Explanation

Step 1:

Since denominators are same, adding the numerators

$\frac{2}{3}$ + $\frac{7}{3}$ = $\frac{(2+7)}{3}$ = $\frac{9}{3}$

Step 2:

Reducing to the lowest terms, $\frac{9}{3}$ = $\frac{3}{1}$ = 3

Step 3:

So, $\frac{2}{3}$ + $\frac{7}{3}$ = $\frac{3}{1}$ = 3

Q 7 - Subtract $\frac{8}{6}$$\frac{4}{6}$

Answer : A

Explanation

Step 1:

Since denominators are same, subtracting the numerators

$\frac{8}{6}$$\frac{4}{6}$ = $\frac{(8−4)}{6}$ = $\frac{4}{6}$

Step 2:

Reducing to the lowest terms, $\frac{4}{6}$ = $\frac{2}{3}$

Step 3:

So, $\frac{8}{6}$$\frac{4}{6}$ = $\frac{2}{3}$

Answer : D

Explanation

Step 1:

Since denominators are same, adding the numerators

$\frac{4}{8}$ + $\frac{2}{8}$ = $\frac{(4+2)}{8}$ = $\frac{6}{8}$

Step 2:

Reducing to the lowest terms, $\frac{6}{8}$ = $\frac{3}{4}$

Step 3:

So, $\frac{4}{8}$ + $\frac{2}{8}$ = $\frac{3}{4}$

Q 9 - Add $\frac{2}{15}$ + $\frac{3}{15}$

Answer : C

Explanation

Step 1:

Since denominators are same, adding the numerators

$\frac{2}{15}$ + $\frac{3}{15}$ = $\frac{(2+3)}{15}$ = $\frac{5}{15}$

Step 2:

Reducing to the lowest terms, $\frac{5}{15}$ = $\frac{1}{3}$

Step 3:

So, $\frac{2}{15}$ + $\frac{3}{15}$ = $\frac{1}{3}$

Q 10 - Subtract $\frac{5}{10}$$\frac{3}{10}$

Answer : B

Explanation

Step 1:

Since denominators are same, subtracting the numerators

$\frac{5}{10}$$\frac{3}{10}$ = $\frac{(5-3)}{10}$ = $\frac{2}{10}$

Step 2:

Reducing to the lowest terms, $\frac{2}{10}$ = $\frac{1}{5}$

Step 3:

So, $\frac{5}{10}$$\frac{3}{10}$ = $\frac{1}{5}$
