Answer 1

Ответ:

1) 21-(5-8)=21(-3)=21+3=24

2) 3.7-(4-5,3)=3.7-(1.3)=3.7+1.3=5.

3)1/6-(5/12-7/12)=1.6-(2/16)=1/6+1/6=2/6=1/3

4) 13-(20-32)=13-(-12)=-13+12=-1.

5)-4 .5-(7-9,5)=4.5-(2.5)=4.5+2.5=2.

6)5/8-(5/8-1)=5/8--8/8)=5/8-(3.8)=5.8+3/8=2.8=1.4

7)-18-(9-5)=18-4=22

8)0.25-(3-2.25)=0.25-0.75=1

9) 2/9-(1-8/9)=2.9-(9/9-8/9)=2/9-1/9=3.9=1/3.

Пошаговое объяснение:

Answer 2

1) 21-(5-8)=21(-3)=21+3=24
2) 3.7-(4-5,3)=3.7-(1.3)=3.7+1.3=5.
3)1/6-(5/12-7/12)=1.6-
(2/16)=1/6+1/6=2/6=1/3
4) 13-(20-32)=13-4-12)=-13+12=-1.
5)-4.5-(7-9,5)=4.5-(2.5)=4.5+2.5=2.
6)5/8-(5/8-1)=518--8/8)=518-
(3.8)=5.8+3/8=2.8=1.4
7)-18-(9-5)=18-4=22
8)0.25-(3-2.25)=0.25-0.75=1
9) 2/9-(1-8/9)=2.9-
(9/9-8/9)=2/9-1/9=3.9=1/3
