Correct Answer: 6.06
Explanation:
Given Exp. = 247 + 353 + 0.05
= 5 + (47 / 99) + (53 / 99) + (05 / 99)
= 5 + (105 / 99)
= 5+106/99
=606/99
= 6.06
Correct Answer: 411/90
Explanation:
4.12 = 4 + 0.12
= 4 + (12 - 1) / 90
= 411/90
Correct Answer: 22 / 3
Explanation:
0.6 + . 7 + .8 + .3
= ( 6/9 + 7/9 + 8/9 + 3/9)
= 24 / 9
= 8 / 3
= 22/3
Correct Answer: 73 / 77
Explanation:
a / b = 0.04 / 1.5
= 4 / 150
= 2 / 75
? Given Exp. (b - a) / ( b + a)
= (1- a/b ) / (1 + a/b)
= (1- 2 / 75) / (1 + 2 / 75)
= ( 73/75 ) / ( 77/75)
= 73/77
Correct Answer: .025
Explanation:
Given expression = ?0.5 x .5 x a = .5 x .05 x ? b
? ?.025 x a = 0.25 x ? b
? 0.025a = 0.25 x .025 x b
? a/b = (.025 x .025) /.025
= .025
