Question

6 by 15 + (-7 )by 25​

Answer 1

Answer:

Step-by-step explanation:

Hi, my friend,

Given that:

$\frac{6}{15} + \frac{-7}{25} \\\\=>\frac{6}{15} - \frac{7}{25}$

LCM of 15,25 is 75.

Therefore

$\frac{6(5)}{15(5)} - \frac{7(3)}{25(3)} \\\\=> \frac{30}{75} - \frac{21}{75} \\\\=> \frac{30-21}{75} \\\\=> \frac{9}{75}$

Hence

The answer is 9/75.

Which is 0.12.
