Fractions and Decimals If 1.5x = 0.04y, then the value of ( (y - x) / (y+x) ) is : 61/63 65/67 71/74 73/77 61/63 65/67 71/74 73/77 ANSWER EXPLANATION DOWNLOAD EXAMIANS APP x / y = 0.04 / 1.5 = 4 / 150 = 2 / 75.= > ( (y - x) / (y+x) ) = (1 - (x / y)) / ( 1 + ( x / y)) = (1 - 2/75) / (1 + 2/75) = 73/77.
Fractions and Decimals By how much does 7/(8/9) exceeds (7/8)/9 ? 8 7/9 6 7/9 7 7/9 5 7/9 8 7/9 6 7/9 7 7/9 5 7/9 ANSWER EXPLANATION DOWNLOAD EXAMIANS APP Here, we have to find the value of 7/(8/9) - (7/8)/9.(7 x 9/8) - [(7/(8 x 9)]63/8 - 7/72[(63 x 9) - 7] / 72567 - 7/72 = 560/72 = 70/9 = 7 7/9.Hence, 7/(8/9) is greater than (7/8)/9 by 7 7/9.
