Question

10-(3 5/6+1 8/11)+4 2/11=

Answer 1

10- (3 55/66 + 1 48/66) + 4 2/11= 10- 5 37/66 + 4 12/66= 9 66/66 - 5 37/66 + 4 12/66= 4 29/66 + 4 12/66= 8 41/66

Answer 2

Ответ:

Пошаговое объяснение:

$\displaystyle 10 -( 3\frac{5}{6} + 1 \frac{8}{11}) + 4 \frac{2}{11}= 8 \frac{41}{66} \\ \\ \\ 1) 3\frac{5}{6} + 1 \frac{8}{11}= (3+1)+(\frac{5}{6} +\frac{8}{11})= 4+ ( \frac{5*11 +8*6}{6*11})= 4 +( \frac{55+48}{66})= 4+ \frac{103}{66}= 4+1\frac{37}{66}= 5 \frac{37}{66}\\ \\ \\ 2) 10 -5 \frac{37}{66}= 9 \frac{66}{66}- 5 \frac{37}{66}= 4 \frac{29}{66}$

$\displaystyle 3) 4\frac{29}{66} + 4\frac{2}{11}= 4 \frac{29}{66} + 4 \frac{2*6}{11*6}= 4\frac{29}{66}+ 4 \frac{12}{66}= 8 \frac{41}{66}$
