Question

If two third of a rational no. exceeds its three fifths by 7/4, find the rational no.

Answer 1

Let the ration number be x
So,
two-third of x will be = 2/3 x
three-fifth of x = 3/5 x
so,
2/3 x - 3/5 x = 7/4
x (2/3 - 3/5) = 7/4
x (10/15 - 9/15) = 7/4
x ( 1/15) = 7/4
x = 7/4 * 15 
x = 105/4

Therefore, rational number is 105/4

Answer 2

Answer:

its dam easy

Step-by-step explanation:

Let the ration number be x

So,

two-third of x will be = 2/3 x

three-fifth of x = 3/5 x

so,

2/3 x - 3/5 x = 7/4

x (2/3 - 3/5) = 7/4

x (10/15 - 9/15) = 7/4

x ( 1/15) = 7/4

x = 7/4 * 15  

x = 105/4

Therefore, rational number is 105/4
