1.	Express the following as decimal fractions.(i) 27%(ii) 6.3%(iii) 32%(iv) 0.25%(v) 7.5%(vi) 1/8%
Answer» (i) 27% To convert percentage to decimal fractions we have to divide by 100, i.e., 27% = 27/100 = 0.27 (ii) 6.3% Here 6.3 can be written as 63/10 To convert percentage to decimal fractions we have to divide by 100, i.e., 6.3% = 63/(10 × 100) =63/1000 = 0.063 (iii) 32% To convert percentage to decimal fractions we have to divide by 100, i.e., 32% = 32/100 = 0.32 (iv) 0.25% Here 0.25 can be written as 25/100 To convert percentage to decimal fractions we have to divide by 100, i.e., 0.25% = 25/(100 × 100) = 25/10000 = 0.0025 (v) 7.5% Here 7.5 can be written as 75/10 To convert percentage to decimal fractions we have to divide by 100, i.e., 7.5% = 75/(10 × 100) =75/1000 = 0.075 (vi) 1/8% To convert percentage to decimal fractions we have to divide by 100, i.e., 1/8% = 1/(8 × 100) =1/800 = 0.00125
