By how much does 7/(8/9) exceeds (7/8)/9 ?

6 7/9
5 7/9
7 7/9
8 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.
