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 $HCF$ of $180 \& 45$, we get:
$\Rightarrow\text{x}=\frac{180\div45}{45\div45}$
$\text{x}=4$

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 $x$.
$6\frac{7}{15}+\text{x}=8\frac{1}{5}$
$\Rightarrow\frac{6\times15+7}{15}+\text{x}=\frac{8\times5+1}{5}$
$\Rightarrow\frac{97}{15}+\text{x}=\frac{41}{5}$
$\Rightarrow\text{x}=\frac{41}{5}-\frac{97}{15}$
$\Rightarrow\text{x}=\frac{41\times3}{5\times3}-\frac{97\times1}{15\times1}$
$\Rightarrow\text{x}=\frac{123}{15}-\frac{97}{15}$
$\Rightarrow\text{x}=\frac{123-97}{15}$
$\Rightarrow\text{x}=\frac{26}{15}$
$\Rightarrow\text{x}=\frac{15+11}{15}$
$\Rightarrow\text{x}=\frac{15}{15}+\frac{11}{15}$
$\Rightarrow\text{x}=1+\frac{11}{15}$
