Question

subtract the first rational numbers from the second in each of the following pairs.
a.-2/3,6/7
b.3/-11,-1/11
c.-4/-7,3/-7
give me all answer I will mark you as a brainlist ​

Answer 1

$\huge\mathfrak\blue{Answer:}$

Rational Number:

• Rational Number are the numbers that can be written in the form of a/b where a and B are integers and b is not equal to zero
• For ex : 2/3 , 3/5 , 5/7 etc

Solution:

We have to subtract the given rational number from one another

$\odot \: \boxed{\sf{Subtracting \: \dfrac{-2}{3} \: from \: \dfrac{6}{7}}}$

• $\mapsto \sf{\dfrac{6}{7} - \left ( \dfrac{-2}{3} \right ) }$

• $\mapsto \sf{\dfrac{6}{7} + \dfrac{2}{3} }$

• Taking LCM on RHS

• $\mapsto \sf{\dfrac{6 \times 3 + 2 \times 7}{21} }$

• $\mapsto \sf{\dfrac{18 + 14}{21} }$

• $\mapsto \sf{\dfrac{32}{21} \: \: }$✔

$\sf{ }$

Moving to the next Question which is :

$\odot \: \boxed{\sf{Subtracting \: \dfrac{3}{-11} \: from \: \dfrac{-1}{11}}}$

• $\mapsto \sf{\left ( - \dfrac{1}{11} \right ) - \left ( -\dfrac{3}{11} \right ) }$

• $\mapsto \sf{\dfrac{3}{11} - \dfrac{1}{11} }$

• $\mapsto \sf{\dfrac{2}{11} \: \: }$✔

$\sf{ }$

Moving to the next Question which is :

$\odot \: \boxed{\sf{Subtracting \: \dfrac{-4}{-7} \: from \: \dfrac{3}{-7}}}$

• $\mapsto \sf{\left ( \dfrac{3}{-7} \right ) - \left (\dfrac{-4}{-7} \right ) }$

• $\mapsto \sf{\dfrac{3}{7} -\dfrac{4}{7} }$

• $\mapsto \sf{-\dfrac{1}{7} \: \: }$✔
