Question

- 3/8+5/12+(-2/3)+5/16​

Answer 1

ответ: -5/16 вот правильно

Answer 2

To add these fractions, you'll need to find a common denominator and then add the numerators.

The common denominator for 8, 12, 3, and 16 is 48, so let's rewrite each fraction with a denominator of 48:

• $\frac{3}{8} = \frac{3 \cdot 6}{8 \cdot 6} = \frac{18}{48}$
• $\frac{5}{12} = \frac{5 \cdot 4}{12 \cdot 4} = \frac{20}{48}$
• $\frac{-2}{3} = \frac{-2 \cdot 16}{3 \cdot 16} = \frac{-32}{48}$
• ( \frac{5}{16} = \frac{5 \cdot 3}{16 \cdot 3} = \frac{15}{48} )

Now, we can add these fractions:

$\frac{18}{48} + \frac{20}{48} + \frac{-32}{48} + \frac{15}{48}$

When you add the numerators:

$18 + 20 - 32 + 15 = 21$

So, the result is:

$\frac{21}{48}$

You can simplify this fraction by finding the greatest common divisor (GCD) of the numerator and denominator, which is 3:

$\frac{21/3}{48/3} = \frac{7}{16}$

So, the final result is $\frac{7}{16}$.
