Question

the numerator of a fraction is 5 less than it's denominator. if 3 added to the numerator and denominator both, the fraction becomes 4/5. find the orginal fraction

Answer 1

i think denominator is 3.5 and numerator is -1.50

x-5/x+3/3=4/5

lcm of 3 and 5 =15

=12/20-15/15

=-3/5=x-5/x

5=x-5+3/x

x=7/2

=3.5

x-5=3.5-5

= -1.5
