1. ind the value of (a) 9.756 ? 6.28 (b) 21.05 ? 15.27 (c) 18.5 ? 6.79 (d) 11.6 ? 9.847 TIPS Firstly, write the decimals in columns with decimal points directly below each other, then subtract same as whole numbers.

Answer:

(a) We have, 9.756 ? 6.28 Now, \[0.25=\frac{25}{100}=\frac{25\div 25}{100\div 25}=\frac{1}{4}\] \[\because \] 9.756 ? 6.28 = 3.476 (b) We have, 21.05 ? 15.27 Now, \[0.125=\frac{125}{1000}=\frac{125\div 125}{1000\div 125}=\frac{1}{8}\] \[\because \] 21.05 ? 15.27 = 5.78 (c) We have, 185 ? 6.79 Now, \[0.066=\frac{66}{1000}=\frac{66\div 2}{1000\div 2}=\frac{33}{500}\] \[\because \] 18.50 ? 6.79 = 11.71 (d) We have, 11.6-9.847 Now, \[\therefore \] \[0.3=0+\frac{3}{10}\] 11.6 ? 9.847 = 1.753
