Answer 1

Answer:

HEY HERE IS YOUR ANSWER

Step-by-step explanation:

Let the number be "x" which is to be added to 4/5 to get 5/4

Then, according to the given condition;

4/5 + x = 5/4

=> x = 5/4 - 4/5

=> x = 9/ 20

Or,

the number which when added to 4/5 gives 5/4 is 9 / 20

Answer 2

Answer:

9/20 is the number to be added

Step-by-step explanation:

1'st number = 4/5

Number to be added = X

2'nd number = 5/4

So,

$\frac{4}{5}+X= \frac{5}{4}$

$X = \frac{5}{4} - \frac{4}{5}$

LCM of 5 and 4 is 20

So,

$X = \frac{25-16}{20}$

$X = \frac{9}{20}$

Hence the number to be added to 4/5 to get 5/4 is 9/20

Check

$\frac{4}{5} + \frac{9}{20} = \frac{5}{4}$

$\frac{16+9}{20} = \frac{5}{4}$

$\frac{5}{4} = \frac{5}{4}$

Hence checked
