Answer 1

Ответ:

$\sqrt{179}$.

1) -2 + (-4) = -6

2) -0.37 + (-0,94) = -1.31

3) -4.72 + (-0.8) = -4.8

4) $-3\frac{6}{11}$ + ($-5\frac{7}{11}$) = $-9\frac{2}{11}$

5)$-\frac{7}{9}$ + ($-\frac{11}{15}$) =$-\frac{35}{45}$+($-\frac{33}{45}$) =$-\frac{68}{45}$=$-1\frac{23}{45}$

6) $-3\frac{11}{12}$+($-4\frac{9}{16}$)=$-3\frac{176}{192}$+($-4\frac{108}{192}$)=$-7\frac{284}{192}$=$-8\frac{92}{192}$=$-8\frac{23}{48}$

$\sqrt{180}$

1) -14 + 8 = -6

2) -2.7 + 6.4 = 3.7

3) 16.8 + (-9.5) = 16.8 - 9.5 = 7.3

4) 7.23 + (-18.4) = - 11.17

5) -9.4 -9.4 = - 18.8

6) -1 + 0.837 = 0.163

7) -5/6 + 7/8 = -40/48 + 42/48 = 2/48 = 1/24

8) $3\frac{7}{8}$ +( $-2\frac{1}{9}$) = $3\frac{63}{72}$ +($-2\frac{8}{72}$) =$1\frac{55}{72}$

9) $-6\frac{2}{9}$+$2\frac{5}{6}$=$-6\frac{12}{36}$+$2\frac{20}{36}$=$-5\frac{48}{36}$+$2\frac{20}{36}$=$-3\frac{28}{20}$=$-4\frac{2}{5}$

$\sqrt{181}$

1) (16.23 + (-1.7)) + (-12,41) = 14.53 + (-12,41) = 2,12

2) $2\frac{1}{6} + (-2\frac{1}{4} + ( -3\frac{3}{5} )) = 2\frac{1}{6} + (-2\frac{5}{20} + ( -3\frac{12}{20})) =2\frac{1}{6} + (-5 \frac{17}{20} ) = 1\frac{70}{60} + (-5\frac{51}{60}) = -4\frac{21}{60} = -4\frac{7}{20}$
