Question

find the rational no. which in standard form is equal to 4/5 and the sum of its numerotor and denominator is 27​

Answer 1

Answer:

12/15

Step-by-step explanation:

let, two no. be x and y

given, x+ y=17

           x/y=4/5

x+ y=27

or, x=27-y... eq I

x/y=4/5

or,5x=4y

or,5(27-y)=4y            put x=27-y

or,135=4y+5y

or,135/9=y

y=15               put y=15 in eq i

x=27-15

x=12
