Question

A rational number between
1\2 and 3\4 is
1)2/5
2)5/8
3)4/3
4)1/4
Please tell me which option is correct
​​

Answer 1

Answer:

1/2 = 0.5

3/4 = 0.75

Now,

2/5 = 0.25

5/8 = 0.625

4/3 = 1.3333

1/4 = 0.25

So.., rational number between 1/2 and 3/4 = 5/8

Answer 2

Answer:

The rational number between a and b is (a + b)/2

Hence rational number between 1 and 2 is (1+2)/2 = 3/2 = 1.5

Rational number between 1 and 3/2 is [1+(3/2)]/2 = 5/4 = 1.25

Rational number between 1 and 5/4 is [1+(5/4)]/2 = 9/8 = 1.125

Rational number between 3/2 and 2 is [(3/2) + 2]/2 = 7/4= 1.75

Therefore four rational numbers between 1 and 2 are 9/8, 5/4, 3/2, and 7/4
