If the numerator of a fraction is increased by 3, the fraction becomes 3/4. if the denominator is decreased by 7, the fraction becomes 1. determine the original fraction. which of the following equations represents "if the numerator of a fraction is increased by 3, the fraction becomes 3/4"?

For this case, the original fraction is:
 x / y
 Where,
 x = numerator
 y = denominator:
 If the numerator of a fraction is increased by 3, the fraction becomes 3/4:
 (x + 3) / y = 3/4
 If the denominator is decreased by 7, the fraction becomes 1:
 x / (y-7) = 1
 Solving the system of equations we have:
 x = 9
 y = 16
 The original fraction is:
 9/16
 
 the original fraction is:
 9/16
 "If the numerator of a fraction is increased by 3, the fraction becomes 3/4" is:
 (x + 3) / y = 3/4

The elephant is 6 feet tall. 15 divided by 2 1/2 is 6. To check multiply 6 and 2 1/2 you get 15. So the elephant is 6 feet tall.
