Answer 1

А) =240÷80=3;

b) =710+290=1000;

e) =4-2=2

f) =21×9=189

C) =2,3+3,7=6;

G) =81÷5=16,2;

D) =0,1×10=1;

H) =3+4=7

Answer 2

Sure, let's solve each of the given expressions step by step.

A) $|240| : |-80| = \frac{240}{80} = 3$

B) $|-710| + |-290| = 710 + 290 = 1000$

E) $|-4| - |-2| = 4 - 2 = 2$

F) $|-21| \times 9 = 21 \times 9 = 189$

C) $|2,3| + |-3,7| = 2.3 + 3.7 = 6$

G) $|-81| : 5 = \frac{81}{5} = 16.2$

D) $|0.1| \times |-10| = 0.1 \times 10 = 1$

H) $|-3| + |4.5| = 3 + 4.5 = 7.5$

Please note that the symbol "|" represents the absolute value or modulus of a number, which is the non-negative value of the number regardless of its sign.
