Example Question #1541 : Grade 6

Solve:

$\begin{array}{r}\overset{\ ~}{ 2 } \overset{\ ~}{ 5 .}\overset{\ ~}{ 1 } 6 \\ + \overset{\ ~ }{ 4 }\overset{\ ~ }{ 7 .}\overset{ }{ 8 } \overset{~\ }{ 0 } \\ \hline \end{array}$

Correct answer:

72.96

Explanation:

When we add with multi-digit numbers with decimals, we start with the numbers furthest to the right and work our way towards the left.

Add the numbers in the hundredths place:

6 + 0 = 6

Your work should look something like this:

$\begin{array}{r}\overset{\ ~}{ 2 } \overset{\ ~}{ 5 .}\overset{\ ~ }{ 1 } 6 \\ + \overset{\ ~ }{ 4 }\overset{\ ~ }{ 7 .}\overset{ }{ 8 } \overset{~\ }{ 0 } \\ \hline \space{} \, \space{\, } \space{\, } 6 \end{array}$

Add the numbers in the tenths place:

1 + 8 = 9

Your work should look something like this:

*Notice that the decimal moves directly down when we are adding decimal numbers.

$\begin{array}{r}\overset{\ ~}{ 2 } \overset{\ ~ }{ 5 .}\overset{\ ~ }{ 1 } 6 \\ + \overset{\ ~ }{ 4 }\overset{\ ~ }{ 7 .}\overset{ }{ 8 } \overset{~\ }{ 0 } \\ \hline \space{} \, \space{\,. } 9 \space{\, } 6 \end{array}$

Add the numbers in the ones place:

5 + 7 = 12

Because this sum is greater than 9, we write the 2 from the ones place and carry the 1 from the tens place over to the left. Your work should look something like this:

$\begin{array}{r}\overset{\ 1 }{ 2 } \overset{\ ~ }{ 5 .}\overset{\ ~ }{ 1 } 6 \\ + \overset{\ ~ }{ 4 }\overset{\ ~ }{ 7 .}\overset{ }{ 8 } \overset{~\ }{ 0 } \\ \hline \space{} \, 2 \space{\,. } 9 \space{\, } 6 \end{array}$

Add the numbers in the tens place including the one carried over:

2 + 4 + 1 = 7

Your final answer should be: 72.96

$\begin{array}{r}\overset{\ 1 }{ 2 } \overset{\ ~ }{ 5 .}\overset{\ ~ }{ 1 } 6 \\ + \overset{\ ~ }{ 4 }\overset{\ ~ }{ 7 .}\overset{ }{ 8 } \overset{~\ }{ 0 } \\ \hline 7 \space{} \, 2 \space{\,. } 9 \space{\, } 6 \end{array}$

Add the numbers in the tens place including the one carried over:

2 + 2 + 1 = 5

Your final answer should be: 51.85

$\begin{array}{r}\overset{\ 1 }{ 2 } \overset{\ ~ }{ 6 .}\overset{\ ~ }{ 3 } 5 \\ + \overset{\ ~ }{ 2 }\overset{\ ~ }{ 5 .}\overset{ }{ 5 } \overset{~\ }{ 0 } \\ \hline 5 \space{} \, 1 \space{\,. } 8 \space{\, } 5 \end{array}$
