How do you find out the numerator wen we know the denominator and percentage?
If you know that n/d = p% where d and p are known, then n = d*p/100.
When your dividing a whole number by a fraction with a numerator of 1 how do you fing the quotient?
Suppose n is a whole number and the fraction is 1/d where d is also a whole number.Then n / (1/d) = n * (d/1) = n*dFor example, 7 / (1/5) = 7*(5/1) = 7*5 = 35

Denominator of a rational no is greater than its numerator by 7 if the denominator is decreased by 6 and the numerator is increased by 17 the new no becomes 2 what is the original no.?
d = n + 7 and (n + 17)/(d - 6) = 2 so (n + 17)/ n + 7 - 6 = 2 (n + 17)/(n + 1) = 2 2n + 2 = n + 17 n = 15 and d = 22 Check n + 17 = 32, d - 6 = 16, 32/16 = 2 Original number is 15/22
