Answer 1

Answer- The above question is from thee chapter 'Comparing Quantities'.

Given question: Attempt the following questions:-

1. Convert $\frac{47}{100}$ into Percentage.

2. Convert $\frac{9}{20}$ into Percentage.

3. Convert $6 \frac{1}{4} \%$ into Fraction.

4. Convert 120 % into Fraction.

5. Express 43 % as a Ratio.

6. Express 7.5 % as a Ratio.

7. Convert 16:25 into Percentage.

8. Find the simple interest on ₹ 4000 for 4 years at the rate of 5 % p.a.

9. Find 32 % of 425.

10. If 3 % of x is 9, then find x.

11. Convert 45 % in decimal form.

12. Convert 0.6 into Percentage.

Solution: 1. $\frac{47}{100}$ into Percentage =  $\frac{47}{100} \times 100$

$\frac{47}{100}$ into Percentage = 47 %                                                                                  

2. $\frac{9}{20}$ into Percentage = $\frac{9}{20} \times 100$

$\frac{9}{20}$ into Percentage = 9 × 5 = 45 %

3. $6 \frac{1}{4} \%$ into Fraction = $\frac{25}{4} \times \frac{1}{100}$

$6 \frac{1}{4} \%$ into Fraction = $\frac{1}{16}$

4. 120 % into Fraction = 120 × $\frac{1}{100}$

120 % into Fraction = $\frac{12}{10}$

120 % into Fraction = $\frac{6}{5}$

120 % into Fraction = $1 \frac{1}{5}$

5. 43 % as Ratio = $\frac{43}{100}$

43 % as Ratio = 43 : 100

6. 7.5 % as Ratio = $\frac{7.5}{100}$

7.5 % as Ratio = $\frac{75}{1000}$

7.5 % as Ratio = $\frac{3}{40}$

7.5 % as Ratio = 3 : 40

7. 16 : 25 into Percentage = $\frac{16}{25} \times 100$

16 : 25 into Percentage = 16 × 4 = 64 %

8. Principal (P) = ₹ 4000

Time (T) = 4 years

Rate of Interest p.a. (R) = 5 %

Simple Interest (S.I.) = $\frac{P \times R \times T}{100}$

S.I. = $\frac{4000 \times 5 \times 4}{100}$

S.I. = ₹ 800

9. 32 % of 425 = $\frac{32}{100} \times 425$

32 % of 425 = 8 × 17 = 136

10. 3 % of x = 9

$\frac{3}{100} \times x \: = 9$

x = 300

11. 45 % in decimal form = $\frac{45}{100}$

45 % in decimal form = 0.45

12. 0.6 into Percentage = 0.6 × 100

0.6 into Percentage = $\frac{6}{10} \times 100$

0.6 into Percentage = 60 %
