Given : a) 60.92×2.09
b) 79.1x3.5
c) 307.09×3.5
d) 694.32x9.81
To Find: Products
Solution:
60.92×2.09
= (6092/ 100) * (209/100)
= (6092 * 209) / (100 * 100)
6092 * 209
= (6100 - 8) ( 200 + 9)
= 6100 * 200 + 6100 * 9 - 8 * 200 - 8 * 9
= 1220000 + 54900 - 1600 - 72
= 1274900 - 1672
= 12,73,228
100 * 100 = 10000
12,73,228 /10000
= 127.3228
60.92×2.09 = 127.3228
Similarly
b) 79.1x3.5 = 276.85
c) 307.09×3.5 = 1,074.815
d) 694.32x9.81 = 6,811.2792
