Question

-5/6+а, если а=-15,3

Answer 1

Ответ:

$- 14 \frac{7}{15}$

Пошаговое объяснение:

$\frac{5}{6} + a$

При а=-15.3

$\frac{5}{6} + ( - 15.3) = \frac{5}{6} - 15.3 = - 15.3 + \frac{5}{6} = - 15 \frac{3}{10} + \frac{5}{6} = - 15 \frac{18 - 50}{60} = - 14 \frac{78 - 50}{60} = - 14 \frac{28}{60} = - 14 \frac{7}{15}$

Answer 2

To find the value of $-\frac{5}{6} + a$ when $a = -15.3$, you can substitute the value of $a$ into the expression:

$-\frac{5}{6} + a$

Substitute $a = -15.3$:

$-\frac{5}{6} + (-15.3)$

To add these two terms, you need a common denominator. The common denominator is 6 in this case. So, multiply the numerator and denominator of $-\frac{5}{6}$ by 6:

$-\frac{5 \times 6}{6 \times 6} - 15.3$

Simplify the expression:

$-\frac{30}{36} - 15.3$

Now, subtract the fractions:

$-\frac{30}{36} - \frac{544.8}{36}$

Combine the terms:

$-\frac{574.8}{36}$

Now, simplify the fraction if possible. The numerator and denominator have a common factor of 2:

$-\frac{287.4}{18}$

So, when $a = -15.3$, $-\frac{5}{6} + a$ is equal to $-\frac{287.4}{18}$.
