Question

what number should be added to 5/10 to get 27/8​

Answer 1

• So, 7/36 must be added to 1/4 to get 4/9.

Answer 2

let number added to 5/10 to get answer 27/8 be x

5/10+x=27/8                               on transposing 5/10 to RHS

x=27/8-5/10                                LCM of 8 and 10= 40

x=(27*5-5*4)/40

x= (135-20)/40

x=115/40

x=2.875       ans
