Question

Explain how you would find the sum of 4.2 and 2.14

Answer 1

The simplest way to add is by adding by place value, then adding them together.

Start with the hundredths. .04+.00=.04
Then the tenths. .2+.2=.3
Finally, the ones. 4+2=6

Add the results together to get the final answer. 
.04+.3+6= 6.34

Answer 2

4.20 + 2.14 = 6.34 :))
