? 9 x 8=72
? 0.09 x 0.008 = 0.00072 (Five place of decimal )
Let 0.8y = 0.0004
Then,y = 0.0004 / 0.8
= 0.004 / 8
= .0005
Here 5 x 25 x 6301 x 394=310324250
Total decimal places = (2+3+5) = 10
? 5 x 0.25 x 6.301 x 0.00394 = 0.0310324250
9.724 ÷ 100 = 0.09724
Shift decimal two palaces to the left. i.e 100
Multiplying 3.242 x 14=4.5388
Now divide 4.5388 by 100
So, 4.5388 ÷ 100= 0.045388
? Shift the decimal two places to the left as 100
For the product of 3.5413 x 2.1
Consider 35413 x 21 = 743673
Total decimal places = 4 + 1
? 3.5413 x 2.1=7.43673
0.000033 / 0.11 = 0.0033 / 11 =.0003
25 / .0005 = 250000 / 5 = 50000
