Sagot :

Answer:

1.) Yes

2.)No

3.)Yes

4.)No

Step-by-step explanation:

1.) 12.5 - 8.4 = 4.1

4.1 x 7.4 = 30.34

7.4 x 4.1 = 30.34

2.)24 - 1.6 = 22.4

22.4 / 3.2 =7

6.4 / 3.2 = 2

7 does not equal 2

3.) 7.4 + 12.5 = 19.9

19.9 - 8.4 = 11.5

7.4 + 4.1 = 11.5

11.5 = 11.5

4.)8 x 2.5 = 20

20 - 3.2 = 16.8

20 + 4.1 = 24.1

24.1 does not equal 16.8
