Fractions and Decimals If √5 = 2.24, then the value of 3√5 / 2√5 - 0.48 is ? 1.68 168 None of these 16.8 1.68 168 None of these 16.8 ANSWER EXPLANATION DOWNLOAD EXAMIANS APP Given expression = 3√5 / 2√5 - 0.48= (3 x 2.24) / (2 x 2.24) - 0.48= 6.72 / 4.48 - 0.48 = 6.72 / 4 = 1.68
Fractions and Decimals There are two fractions such that fraction X is thrice the fraction Y and their product is 25/12. Which of the following is equal to Y? 9/10 5/6 3/4 7/8 9/10 5/6 3/4 7/8 ANSWER EXPLANATION DOWNLOAD EXAMIANS APP Let X and Y are given fractions.Given that, fraction X is thrice the fraction Y;i.e., X = 3Y ...(1)And their product = X x Y = 25/12Sub. eqn (1) in above,(3Y)x(Y) = 25/123(Y²) = 25/12(Y²) = 25/36Y = 5/6Hence the required fraction is 5/6.
