Mark the correct alternative of the following:If $\frac{45}{60}$ is equivalent to $\frac{3}{\text{x}},$ then $x =$
Answer$\frac{45}{60}=\frac{3}{\text{x}}$
On cross $-$ multiplying, we get:
$45\times\text{x}=3\times60$
$\Rightarrow\text{x}=\frac{3\times60}{45}$
$\Rightarrow\text{x}=\frac{180}{45}$
On dividing the numerator denominator by the $\text{HCF}$ of $180 ,45,$ we get:
$\Rightarrow\text{x}=\frac{180\div45}{45\div45}$
$\text{x}=4$

- A
$15.15$ litres.
- B
$15.150$ litres.
- C
$15.0015$ litres.
- ✓

$15\text{ ml}=\frac{15}{1000}=0.015\text{ litre}$
So, $15\text{ litre}$ and $15\ ml$
$= 15\text{ litre} \ + \ 0.015\text{ litre}$
$= 15.015\text{ litre}$.

Which is greater among $2.3, 2.03, 2.33, 2.05?$
- A
$2.3$
- B
$2.03$
- ✓
$2.33$
- D
$2.05$
AnswerCorrect option: C. $2.33$
The whole parts of all the above numbers are equal. Comparing the tenth parts, we see that two of the decimals have a tenth part $0$ and two have a tenth part $3.$ Leaving aside the decimals that have a tenth part $0,$ we have $2.3$ and $2.33.$ Comparing them, we find that $2.33$ is greater than $2.3,$ because, in $2.3,$ there is no hundredth part, but in $2.33,$ the hundredth part is $3.$

- A
$\frac{11}{15}$
- ✓
$1\frac{11}{15}$
- C
$\frac{44}{3}$
- D
$\frac{3}{44}$
AnswerCorrect option: B. $1\frac{11}{15}$
Let the fraction to be added is $x.$
$6\frac{7}{15}+\text{x}=8\frac{1}{5}$
$\Rightarrow\frac{6\times15+7}{15}+\text{x}=\frac{8\times5+1}{5}$
$\Rightarrow\frac{97}{15}+\text{x}=\frac{41}{5}$
$\Rightarrow\text{x}=\frac{41}{5}-\frac{97}{15}$
$\Rightarrow\text{x}=\frac{41\times3}{5\times3}-\frac{97\times1}{15\times1}$
$\Rightarrow\text{x}=\frac{123}{15}-\frac{97}{15}$
$\Rightarrow\text{x}=\frac{123-97}{15}$
$\Rightarrow\text{x}=\frac{26}{15}$
$\Rightarrow\text{x}=\frac{15+11}{15}$
$\Rightarrow\text{x}=\frac{15}{15}+\frac{11}{15}$
$\Rightarrow\text{x}=1+\frac{11}{15}$
