Question

Please please please help me! I don't understand division at all I don't know what's wrong with this I'll give brianliest to most helpful and correct answer

Answer 1

Step-by-step explanation:

 a)  

12.3+18=30.3

    1

    12.3

+   18

----------

30.3

The equation is not set up properly. The 8 should be under the 2, as it is in the ones, while the 1 should be under the 1 as it is 10. The way they set it up tricks you to think that there is a decimal (1.8), when it is really 18.

b)

32.1 + 4.6 = 36.7

   32.1

+    4.6

-----------------

36.7

6 + 1 = 7, so the 1 does not have to be carried as it does not equal 10. In this case it is 0.6 + 0.1 = 0.7, it would have to be 1.0 to carry it to the ones.
