| Answer» a) Given number \(\frac{15}{2}\) is in fraction form. To convert the fraction into percent we have to multiply the fraction by 100% \(\frac{15}{2}\) = \(\frac{15}{2}\) × 100 = 15 × 50 = 750% (percent form) b) Given number 8\(\frac{1}{4}\) is in fraction form. To convert the fraction into percent we have to multiply the fraction by 100% 8\(\frac{1}{4}\) = \(\frac{33}{4}\) = \(\frac{33}{4}\) × 100 = 33 × 25 = 825%,(percent form). c) Given number 5\(\frac{3}{4}\) is in fraction form. To convert the fraction into percent we have to multiply the fraction by 100 and assign the percentage symbol % 5\(\frac{3}{4}\) = \(\frac{23}{4}\) × 100 = 23 × 25 = 575% (percent form) d) Given number is 3\(\frac{1}{3}\) in fraction form. To convert the fraction into percent we have to multiply the fraction by 100% 3\(\frac{1}{3}\) = \(\frac{10}{3}\) × 100 = \(\frac{100}{3}\) = 333\(\frac{1}{3}\) % (percent form) | |
| 15. | Rahim works in a software company and earns Rs. 75,000/- per month. He saves Rs. 28,000/- per month from his earnings. Find the ratio of i) His savings to his incomeii) His income to his expenditure iii) His savings to his expenditure |
