Answer 2

Расставим порядок действий

(28 19/21 -¹ 4 19/21) -³ (5 7/11 +² 9 8/11)

1) 28 19/21 - 4 19/21 = 24

2) 5 7/11 + 9 8/11 = -4 1/11

3) 24 - (-4 1/11) = 24 + 4 1/11 = 28 1/11

ОТВЕТ: 28 1/11

Answer 3

I can help you with your math problem. The answer is:

$$\begin{align*} (28+\frac{19}{21}-4+\frac{19}{21})-(5+\frac{7}{11}+9+\frac{8}{11}) &= (24+\frac{38}{21})-(14+\frac{15}{11}) \\ &= \frac{504+38}{21}-\frac{154+15}{11} \\ &= \frac{542}{21}-\frac{169}{11} \\ &= \frac{542 \times 11 - 169 \times 21}{21 \times 11} \\ &= \frac{5962-3549}{231} \\ &= \frac{2413}{231} \\ &= 10+\frac{163}{231} \end{align*}$$
