plzzz solve it fastt​

Answer 1

QuestioN :-

2. Find the two integers between which the given rational numbers lie. Also, find their actual position on a number line.

a) 15 / 17.

b) 12 / 5.

c) - 34 / 16.

d) - 12 / 70.

SolutioN :-

✎ We have, Rational number.

Rational number can be define as a number which can Express in the form of p / q, where q ≠ 0.

✎ Rational number :—

15 / 17.

12 / 5.

- 34 / 16.

- 12 / 70.

$\rule{140}2$

✎ Let's Taking Some Cases, to find greatest integer and least integer.

Out of four given Rational number,

The least rational number is - 34 / 16.

The greatest rational number is 12 / 5.

$\rule{200}2$

☛ Case 1.

For greatest possible integer.

$\tt \mapsto \dfrac{ - 34}{16}$

$\tt \mapsto - 2.125$

✵ Integer form - 3.

$\rule{200}2$

☛ Case 2.

For least possible integer.

$\tt \mapsto \dfrac{ 12}{5}$

$\tt \mapsto 2.4$

✵ Integer form 3.

$\rule{200}2$

${\tt{Note:}}\begin{cases} \sf{The \: least \: possible \: integer} \\ \sf{come \: after \: greater \: rational} \\ \sf{number.}\end{cases}$

$\tt{Note:}\begin{cases} \sf{The \: greater \: possible \: integer} \\ \sf{come \: after \: least \: rational} \\ \sf{number.}\end{cases}$

♢ Given, four rational lies on number line between - 3 , 3.
