Question

What should be added to twice the rational number -7/3 to get 3/7

Answer 1

hii mark as the brainliest need only 4 more

let unknown no be x

atq
x+2*-7/3=3/7
x-14/3=3/7
x=3/7+14/3
x=9+98/21
x=5.0952

mark brainliest pl

Answer 2

Ques:- What should be added to twice the rational number -7/3 to get 3/7

$\star\tt{\large{\underline{\underline{\blue{According\:To\:Question:}}}}}$

_______________________________

Twice the rational number $\frac{ - 7}{3} \: is \: 2 \times ( \frac{ - 7}{3} ) = \frac{ - 14}{3}$

If x is added to the number gives $\frac{3}{7}$

$\large\implies$ $x - \tt\frac{14}{3} = \frac{3}{7}$

$\large\implies$$x = \tt\frac{3}{7} + \frac{14}{3}$

[Transposing $\frac{14}{3}$ to R.H.S]

$\large\implies$$= \tt\frac{(3 \times 3) + (14 \times 7)}{21} = \frac{9 + 98}{21}$

$\large\implies$$= \tt\frac{107}{21}$

Thus, $\tt{\dfrac{107}{21}}$ should be added to $\tt{2\times\dfrac{-7}{3}}$ to give $\tt{\dfrac{3}{7}}$

$\large\bold{\green{\underline{Additional\:information:}}}$

The numbers that can be represented as an integral ratio are called rational numbers.

Examples are

5/4, 4/7, - 7/10, 37/34

Solving equations like

7x + 9 = 0

Then

x = -9/7.

Solution -9/7 is neither a natural number or whole number

The numbers in x/y form; where y≠0 is referred to as the rational number
