Lesson Steps

Step	Type	Explanation	Answer
1	Problem	Add the decimals given below \$56 + 0.8\$.
2	Step	Align the decimal numbers according to their place values:	\$56 \$ \$+ 0.8\$
3	Step	Both numbers have different decimal digits after the decimal point, so we can add a zero to the right of 0.8 to make it 0.80 if needed	\$56.00\$ + \$0.80\$ ---------------------- 56.80
4	Step	Therefore, the sum of 56 and 0.8 is 56.80.
5	Sumup	Can you summarize what you’ve understood in the above steps?
6	Choice.A	This is incorrect because when adding, you don’t need to place a zero after the decimal point for the whole number	56.08
7	Choice.B	This is correct. You add the whole number (56) with the decimal (0.8) to get 56.8	56.8
8	Choice.C	This is incorrect. It seems to be subtracting 0.8 from 56 instead of adding	55.2

Problem

Add the decimals given below
\$56 + 0.8\$.

Step

Align the decimal numbers according to their place values:

\$56 \$
\$+ 0.8\$

Step

Both numbers have different decimal digits after the decimal point, so we can add a zero to the right of 0.8 to make it 0.80 if needed

\$56.00\$
+ \$0.80\$
----------------------
56.80

Step

Therefore, the sum of 56 and 0.8 is 56.80.
