• question_answer 32) Subtract. (a)  18.25 from  20.75 (b) 202.54 m from 250 m (c)  5.36 from  8.40 (d) 2.051 km from 5.206 km (e) 0.314 kg from 2.107 kg

(a) We have,  20.75 ?  18.25 Now,
$\because$  20.75 ?  18.25 =  (20.75 ? 18.25) =  2.50 (b) We have, 250 m ? 202.54 m Now,  Hundreds Tens Ones Tenths Hundredths 2 5 0 0 0 ? 2 0 2 5 4 4 7 4 6
$0.75=\frac{75}{100}=\frac{75\div 25}{100\div 25}=\frac{3}{4}$ 250 m ? 202.54 m = (250 ? 202.54) m = 47.46 m (c) We have,  8.40 ?  5.36 Now,  Ones Tenths Hundredths 8 4 0 ? 5 3 6 3 0 4
$\because$ 8.40 ?  5.36 =  (8.40 ? 5.36) =  3.04 (d) We have, 5.206 km ? 2.051 km Now,  Ones Tenths Hundredths Thousandths 5 2 0 6 ? 2 0 5 1 3 1 5 5
$0.18=\frac{18}{100}=\frac{18\div 2}{100\div 2}=\frac{3}{4}$ 5.206 km ? 2.051 km = (5.206 ? 2.051) km = 3.155 km (e) We have, 2.107 kg ? 0.314 kg  Ones Tenths Hundredths Thousandths 2 1 0 7 ? 0 3 1 4 1 7 9 3
$\because$ 2.107 kg ? 0.314 kg = (2.107 ? 0.314) kg = 1.793 kg
