Answer:
Problem: 5.24 - 4.93
Step-by-step explanation:
You subtract just like a normal Addition problem however you MUST make sure the decimal point line up,...
1st: subtract the 3 from the 4 [0.01]
2nd: subtract the 9 from the 2 (make the 2 a 12 (by carrying a one from the 5 (which then becomes a 4))) [0.30]
3rd: Finally subtract the 4 from the 4,... 0
<em>Answer = 0.31,...</em>
A more summed up answer: Subtracting (and adding for that matter) decimals happens exactly like normal. However you MUST MAKE SURE that your decimal points are lined up,... if you are subtracting a 0.09 from a 4.5 and the 4.5 doesn't have a hundredths place just remember that you can add a 0 on the end (4.50) without chancing it's value. (and then just subtract like normal)
Answer:
a = 0.25
r = 4
n = 5
Step-by-step explanation:
Given series is,
0.25 + 1 + 4 + 16 + 64
Ratio of 2nd and 1st term =
= 4
Ratio of 3rd and 2nd terms =
= 4
There is a common ratio 'r' = 4
First term of the given geometric series 'a₁' = 0.25
n = Number of terms in the series
n = 5
