Question

SIMPLIFY :-
7/9 + (-11/3)
with solution​

Answer 1

Step-by-step explanation:

7/9+(-11/3)

L.C.M of 9,3 =9

7+(-11*3)/9

7-33/9

-26/9

Answer 2

Answer :

$\quad \dashrightarrow \: \: \bf{-\dfrac{26}{9} \: \: \bigstar}$

Step-by-step Explanation :

$\quad \dashrightarrow \: \: \bf{ \dfrac{7}{9} + \bigg\lgroup-\dfrac{11}{3}\bigg\rgroup \: \: \bigstar}$

$\quad \dashrightarrow \: \: \tt{ \dfrac{7}{9}-\dfrac{33}{9} \: \: \bigstar}$

$\quad \dashrightarrow \: \: \tt{ \dfrac{7 - 33}{9}}$

$\quad \longmapsto \: \: {\underline{\boxed{\bf{-\dfrac{26}{9}}}}\: \: \bigstar}$

.°. The answer is $\sf-\dfrac{26}{9}$.

Method Used :

• Least common multiple of 9 and 3 is 9. Convert (7)/(9) and (11)/(3) to fractions with denominator 9 and multiply (+) times (–) to get (–).

• Since (7)/(9) and (33)/(9) have the same denominator, subtract them by subtracting their numerators.

• Subtract 33 from 7 to get -26.

• The equation is solved now !

Find more :

Multiplication of signs :

• (+)(–) = (–).
• (+)(+) = (+).
• (–)(+) = (–).
• (–)(–) = (+).

[ Note : If there are same signs (i.e. (+)(+) or (–)(–)) we get always (+) and if there are different signs (i.e. (+)(–) or (–)(+)) we get always (–) ].
