The product of 10/9 with another number is 7/11. What is the other number?
-------------
(10/9)*n = 7/11
n = (7/11)/(10/9)
Invert the divisor 10/9 and multiply.
n = (7/11)*(9/10)
n = 63/110

The product of 10/9 with another number is 7/11.
What is the other number?
n * 10%2F9 = 7%2F11
%2810n%29%2F9 = 7%2F11
Cross multiply
11*(10n) = 9 * 7
110n = 63
n = 63%2F110
