1 / .003718 = 10000 / 3.718
= 10000 x ( 1/3.718)
= 10000 x .2689
= 2689.
Given expression 280.5 / 25.5 = 2805 / 255
= 2805 / (2.55 x 100)
= 1100 / 100
=11
(.24 x .35) / (.14 x .15 x .02)
= (24 x 35 x 100 ) / (14 x 15 x 2)
=200
11/3 = 0.846,
9/11 = 0.818,
3/4 = 0.75 and
5/7 = 0.714
Clearly, 0.714 is the smallest and hence 5/7 is smallest fraction .
Required decimal = 1/ ( 60 x 60)
= .00027
0.6 + 0.66 + 0.066 + 6.606 = 0.600 + 0.660 + 0.066 + 6.660
= 7.932
Let (20 + 8 x 0.5) / ( 20 - y) =12
Then, 24 =12 x (20 - y)
? 12y = 216
? y = 18
Let Y = 0.15 / (0.5 / 15)
= (15/100) / [(5/100) / 15)
= 4.5
Let (17.28 / y) / (3.6 x 0.2) = 200
Then,17.28 / y = 200 x 3.6 x 0.2
? y = 17.28 / (200 x 3.6 x 0.2)
= 1728 / 200 x 36 x 2
= 0.12.
Let 3420 / 19 = (y / 0.01) x 7
Then , y = ( 3420 / 19) x (0.01 / 7)
= 180 / 700
= 9/35
Given expression = 8.32 x 0.999
= 8.32 x (1-0.001)
= 8.32 - 8.32 x 0.001
=8.32 - .00832
= 8.31168.
