Question

the numerator and the denominator of a fraction are in a ratio of 2:7. if two is added to the numerator and three is added to the denominator, then the new fraction becomes 2/5 . find the original fraction​

Answer 1

Answer:

4/10

Step-by-step explanation:

numerator=2

denominator =7

2+ num=4

3+ deno=10

so the actual fraction is 4/10 which is reduced to 2/5

Answer 2

Answer:

Fraction=2/7

Step-by-step explanation:

Let the numerator be = 2x

denominator=7x

Now according to question

(2x+2)/ (7x+3) = 2/5

cross Multiplication

14x+6= 10x+10

14x - 10x= 10-6

4x= 4

x= 4/4

x= 1

Numerator= 2x

=2×1

=2

Denominator= 7x

= 7×1

=7

so Fraction will be 2/7
