Question

7 plus 5.3 (with explanation?)​

Answer 1

Answer: 12.3
Step-by-step explanation:
Adding 7 + 5.3 is like adding 7.0 + 5.3 but adding 7.0 + 5.3 is visually easier.
Make an equation and make sure the decimal (the dot) is in line.

7 . 0
+ 5 . 3
—————
= ??

You add from left to right, so start with 0 + 3.

7 . 0
+ 5 . 3
—————
= ? . 3

Now add the 7 + 5.

7 . 0
+ 5 . 3
—————
= 12 . 3


Hope this help you under how to do it <3
