Question

2 by 3 and 4 by 5 rational numbers between

Answer 1

2/3=0.6 approxx

4/5=0.8 approx

now number between

0.6 and 0.8

=0.7=7/10

in this way u can find a rational number

hope it help u plzzz mark me brainliest

Answer 2

Given two numbers,

$\frac{2}{3} \:\&\: \frac{4}{5}$

First of all, make both the denominators same. Here, the first denominator is 3 and second denominator is 5. So, multiply both the numbers which a suitable number so that, the denominators should be equal.

We can multiply 5 to the first number and 3 to the second number so that both the denominators will be equal.

$(i) \frac{2 \times 5}{3 \times 5} = \frac{10}{15}$

$(ii) \frac{4 \times 3}{5 \times 3} = \frac{12}{15}$

And as we know, there lie infinite numbers between any two numbers.

Here, the two new numbers are, $\frac{10}{15} \:\&\: \frac{12}{15}$. So, there must be infinite numbers lying between these two numbers. You can write any of them.

The rational number lying between $\frac{10}{15} \:\&\: \frac{12}{15}$ is

$\frac{11}{15}$.
