Question
5.9 + 2.3 =
- 7.12
- 8.2
- 0.82
- 71.2
Hint:
In decimal addition, we need to remember that we need to align the second decimal number in such a way that the decimal point of that number is just below the decimal point of the first number. Then we perform normal addition.
The correct answer is: 8.2
Step by step solution:
Given two decimal numbers are : 5.9 and 2.3
Now, we need to align the numbers in such a way that the decimal point of one number is just below the decimal point of the other number.
5.9
+ 2.3

If each shirt costs $6.90 and you buy 5 of them, then the total cost is _______
Another approach to the question might be that we can just add $6.90 five times since 5 shirts are bought.
Therefore, the total cost = $ (6.90+6.90+6.90+6.90+6.90)
= $ 34.50
Thus, total cost would be $34.50 which is option (a)
