The L.C. M. of 3.0, 0.09 and 2.7 is?

Correct Answer: 100

Explanation:

Given expression = (0.01 - 0.0001) / (0.00001 + 1)
= (.0099 / .0001) + 1
= 99 + 1
= 100

Correct Answer: 1.5

Explanation:

Given expression = 3 / [ 3+ {(0.3 - 3.03) / (3 x 0.91)}]
= 3 / [3- { 273 / (3 x 91)}]
= 3 / (3-1)
= 3 / 2
= 1.5

Correct Answer: 1

Explanation:

Given Expression = ( a³ + b³ )/ (a² + b² - ab) where = 0.87 and b = 0.13
= [(a + b ) (a² + b² - ab)] / (a² + b² - ab)
= a + b
= 0.87 + 0.13
= 1

Correct Answer: 1

Explanation:

Given Expression = (1.04)² + 1.04 x 0.04 + (0.04)² / (1.04)³ - (0.04)³
= (a² + ab + b²) / (a³ - b³)
= (a² + ab + b²) / [(a-b) (a² + ab + b²)]
= 1 / (a - b)
= 1/ (1.04 - 0.04)
= 1

Correct Answer: 0.14

Explanation:

Given expression
= [(0.47)³ - (0.33)³] / [(0.47)² + 0.47 x 0.33 + (0.33)²]
= [a³ - b³ ] / [ a² + ab + b²]
= [(a-b) (a² + ab + b²)] / [(a² + ab + b²)]
= (a - b)
= (0.47 - 0.33)
= 0.14

Correct Answer: .18

Explanation:

The Given Number are 1.08, .36 and 0.9
G. C. D of 108, 36 and 90 is 18
? Required G. C. D. = 0.18

Correct Answer: 3/22

Explanation:

= 0.136
= (136 - 1) / 990
= 135 / 990
= 3 / 22

Correct Answer: 1.01 = ?

Explanation:

Given Exp. = 0.63 + 0.37
= 63/99 + 37/99
= 100 / 99
= 1¹/₉₉
= 1.01

Correct Answer: 0.4801

Explanation:

Given Exp= 0.3467 + 0.1333
= (3467 - 34) / 9900 + (1333 -13) / 9900
= 3433 +1320 / 9900
= 4753 / 9900
= (4801 - 48) / 9900
= 0.4801

Correct Answer: 1.43

Explanation:

Given Exp. = 3.57 - 2.14
= 3 + (57 / 99) - 2 - (14 / 99)
= 1 + (57 / 99) - (14 /99)
= 1 + 43/99
= 1.43
