The numerator of a fraction is 2 less than its denominator. If 3 is substracted from the numerator and from the denominator, the new fraction obtainded is 3/4. Find the fraction

Answer 1

n = numerator

d = denominator

n = d - 2

( n - 3 ) / ( d - 3 ) = 3 / 4

( d - 2 - 3 ) / ( d - 3 ) = 3 / 4

( d - 5 ) / ( d - 3 ) = 3 / 4 Multiply both sides by 4

4 ( d - 5 ) / ( d - 3 ) = ( 3 / 4 ) *4

4 ( d - 5 ) / ( d - 3 ) = 3 Multiply both sides by ( d - 3 )

4 ( d - 5 ) ( d - 3 ) / ( d - 3 ) = 3 ( d - 3 )

4 ( d - 5 ) = 3 ( d - 3 )

4 d - 20 = 3 d - 9 Subtract 3 d to both sides

4 d - 20 - 3 d = 3 d - 9 - 3 d

d - 20 = - 9 Add 20 to both sides

d - 20 + 20 = - 9 + 20

d = 11

n = d - 2 = 9

Numerator = 9

Denumerator = 11

Answer 2

I know what an enumerator does, but I'm not sure what a denumerator does . . . eliminate stuff?

Answer 3

Steve,

I am from Sarajevo, Bosnia and Herzegovina.

English is foreign language for me.

Numerator is typing mistake, so what?

Answer 4

I hav qstion i need answer..
If the numerator of a fractionis multiplied by 4 and the denominatoris reduced by 2,the result is 2.if the numeratorof the fraction is increase by 15 and 2 subtracted from thedouble of the denominator the result is 9/7, find the fraction
