Answer 1

Answer:

Step-by-step explanation:

(3/4+7/4) /2=(3+7/4)/2=10/4/2=10/8=5/2

5/2 is a rational number between 3/4 and 7/4.

Answer 2

Answer:

$A\:Rational\: between \:\frac{3}{4}\:and \:\frac{7}{4}=\frac{5}{4}$

Step-by-step explanation:

We know that,

Any rational number between 'a' and 'b' =$\frac{a+b}{2}$

$Here, a =\frac{3}{4}, \:and \: b = \frac{7}{4}$

$Rational\: between \:\frac{3}{4}\:and \:\frac{7}{4}=\frac{\frac{3}{4}+\frac{7}{4}}{2}\\=\frac{\frac{3+7}{4}}{2}\\=\frac{\frac{10}{4}}{2}\\=\frac{5}{2}\times \frac{1}{2}\\=\frac{5}{4}$

Therefore,

$A\: Rational\: between \:\frac{3}{4}\:and \:\frac{7}{4}=\frac{5}{4}$
