Question

Calculate the following:
$\frac{ - 4 }{5} \times \frac{3}{7} + \frac{4}{5} \times \frac{3}{7}$
​

Answer 1

Answer:

Given to simplify   $\frac{-4}{5} *\frac{3}{7} +\frac{4}{5} *\frac{3}{7}$

    $\frac{-4}{5} *\frac{3}{7} +\frac{4}{5} *\frac{3}{7} =\frac{-12}{35} +\frac{12}{35}$

                           $= 0$

Answer 2

Answer :

• 0.

Step-by-step Explanation :

Given that :

ㅤㅤ→ $\tt \frac{ - 4 }{5} \times \frac{3}{7} + \frac{4}{5} \times \frac{3}{7}$

To do :

• Calculate the following.

Calculating the equation :

ㅤㅤ→ $\tt \frac{ - 4 }{5} \times \frac{3}{7} + \frac{4}{5} \times \frac{3}{7}$

ㅤㅤ→ $\tt - \frac{4 \times 3}{5 \times 7}+ \frac{4}{5} \times \frac{3}{7}$

ㅤㅤ→ $\tt - \frac{12}{35}+ \frac{4}{5} \times \frac{3}{7}$

ㅤㅤ→ $\tt - \frac{12}{35}+ \frac{12}{35}$

ㅤㅤ→ $\tt \frac{12}{35}- \frac{12}{35}$

ㅤㅤ→ $\bf 0$

Method used for solving it :

• Here, multiplying {(-4)/(5)} × {(3)/(7)} to get -{(12)/(35)}.

• Similarly, if we multiply {(4)/(5)} × {(3)/(7)} we get {(12)/(35)}.

• We know that (+) × (–) = (–).

• By subtracting {(12)/(35)} and {(12)/(35)} we get 0.

Multiplication of signs :

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

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