Answer:
The answer is 2592
Step-by-step explanation:
The answer is created by multiplying the answer multiple times
One way of calculating decimal sum is by using partition
8.3 = 8 + 0.3
5.2 = 5 + 0.2
4.36 = 4 + 0.3 + 0.06
42.1 = 42 + 0.1
86.0 = 86
Add the units together: 8 + 5 + 4 + 42 + 86 = 145
Add the tenth together: 0.2 + 0.3 + 0.3 + 0.1 = 0.9
Add the hundredth together: 0.06 (we only have one value in hundredth)
Then add all the answers together: 145 + 0.9 + 0.06 = 145.96
Answer 145.96 is correct to two decimal places
If we want to round this answer to correct significant figures, it would depend on how many significant figures are asked.
For example:
145.96 to one significant figure is 100.00
145.96 to two significant figure is 150.00
145.96 to three significant figure is 146.00
and so on
Correct answer: 146.00 (answer is rounded to three significant figures)
