Fractions and Decimals 892.7 - 573.07 - 95.007 = ? 226.623 230.623 228.623 224.623 226.623 230.623 228.623 224.623 ANSWER EXPLANATION DOWNLOAD EXAMIANS APP Given Expression, 892.7 - (573.07 + 95.007)= 892.7 - 668.077 = 224.623.
Fractions and Decimals 3420 / 19 = ( ? / 0.01) x 7 9/35 9/30 9/45 9/40 9/35 9/30 9/45 9/40 ANSWER EXPLANATION DOWNLOAD EXAMIANS APP Let 3420 / 19 = (y / 0.01) x 7Then , y = ( 3420 / 19) x (0.01 / 7) = 180 / 700 = 9/35
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.
