MCQ 151 Mark

Mark $(\checkmark)$ against the correct answer in the following: The product of two numbers is $\frac{-1}{6}$ If one of them is $\frac{-5}{8}$ the other number is:

A
$\frac{-4}{15}$
✓
$\frac{4}{15}$
C
$\frac{15}{4}$

MCQ 171 Mark

Mark $(\checkmark)$ against the correct answer in the following:
Which is smaller between $\frac{-5}{6}$ and $\frac{-7}{12}?$

✓
$\frac{-5}{6}$
B
$\frac{-7}{12}$
C
$\frac{6}{5}$
D
Cannot be compared.

Answer

Correct option: A.

$\frac{-5}{6}$

Since $\text{LCM}$ of $6$ and $12$ is $12$
$\frac{-5\times2}{6\times}=\frac{-10}{12}$
$\frac{-7\times1}{12\times1}=\frac{-7}{12}$
$\frac{-5}{6}<\frac{-7}{12}$

B
$\frac{-3}{4}$
C
$\frac{-7}{12}$
D
$\frac{7}{12}$

Answer

MCQ 231 Mark

Mark $(\checkmark)$ against the correct answer in the following:
What should be subtracted from $\frac{-3}{4}$ to get $\frac{5}{6}?$

A
$\frac{19}{12}$
✓
$\frac{-19}{12}$
C
$\frac{1}{12}$
D
$\frac{-1}{12}$

Answer

Correct option: B.

$\frac{-19}{12}$

The correct option is $(b).$
Let the number that is to be subtracted be $x.$
$\frac{-3}{4}-\text{x}=\frac{5}{6}$
$\Rightarrow-\text{x}=\frac{5}{6}-\Big(\frac{-3}{4}\Big)$
$\Rightarrow-\text{x}=\frac{5}{6}+\frac{-3}{4}$
$\Rightarrow-\text{x}=\frac{(5\times2)+(3\times3)}{12}$
$\Rightarrow\text{x}=-\frac{19}{12}$
Hence, $\frac{-19}{12}$ should be subtracted from $\frac{-3}{4}$ to get $\frac{5}{6}$
