Question

(-2/5)+(-2/3) please answer the question​

Answer 1

Step 1: Find the LCM of the denominators to make them equal.

LCM of 5 and 3 is 15.

Step 2: Make the denominators equal.

$\frac{-2*3}{5*3} =\frac{-6}{15}$

$\frac{-2*5}{3*5} = \frac{-10}{15}$

Step 3: Add the numerators and let the denominators be the same.

$\frac{-6}{15} +\frac{-10}{15}=\frac{-16}{15}$

∴ $\frac{-2}{5} +\frac{-2}{3} =\frac{-16}{15}$

Additional Information :)

• Subtraction of Fractions

To subtract two fractions we need to find the LCM of the denominators and make them equal. Then we need to subtract the numerator and let the denominator be the same. And finally, if the fraction id required to be simplified to the lowest or standard form we do it.

• Multiplication of Fractions

To multiply two fractions we directly multiply the numerator and the denominator. After that, we simplify it to its lowest or standard form if required.

• Division of Fractions

To divide two fractions we take the reciprocal of the second number and multiply the two fractions. After that, we find the lowest or standard form if required.
