Express the following as a fraction.a) 56% SOLUTION: 56/100=14/25b) 4% SOLUTION: 4/100=1/25c) 0.6% SOLUTION: 0.6/100=6/1000=3/500d) 0.08% SOLUTION: 0.08/100=8/10000=1/1250<br>2.Express the following as decimalsa) 6% SOLUTION: 6% = 6/100=0.06 b) 0.04% SOLUTION: 0.04% = 0.04/100=0.00043 . Express the following as rate percent.i).23/36 SOLUTION: = (23/36*100) % = 63 8/9%ii).6 戮 SOLUTION: 6 戮 =27/4 (27/4 *100) % =675 %<br>4.Evaluate the following: 28% of 450 + 45% of 280 ? SOLUTION: =(28/100) *450 + (45/100) *280 = 28 * 45 / 5 = 252<br>5.2 is what percent of 50? SOLUTION: <b>Formula : (IS / OF ) *100 %</b> = 2/50 *100 = 4% <br>6.陆 is what percent of 1/3?

SOLUTION: 1 metric tonne =10 Quintals So required percentage = (40/(2*10)) *100 % = 200% 8.Find the missing figure . i) ? % of 25 = 2.125 SOLUTION : Let x% of 25 = 2.125. then (x/100) *25 =2.125 x = 2.125 * 4 = 8.5 ii) 9% of ? =6.3 SOLUTION: Let 9 % of x = 6.3. Then 9/100 of x= 6.3 so x = 6.3 *100/7 = 70.9.Which is the greatest in 16 2/3 %, 2/15,0.17? SOLUTION: 16 2/3 % = 50/3 % =50/3 * 1/100 =1/6 = 0.166 2 / 15 =0.133 So 0.17 is greatest number in the given series.10.If the sales tax be reduced from 3 陆 % to 3 1/3 % ,then what differencedoes it make to a person who purchases an article with marked price of RS 8400?
