In order to subtract fractions, we must find a common denominator, then subtract the numerators.
The common denominator (LCM(3, 5)) is 15.
We must multiply the first numerator by 5, because 3*5=15 and the second numerator by 3 because 5*3=15.
We get .
All we need to do now is subtract the numerators: .
The answer is 14/15.
Answer:
5.33
Step-by-step explanation:
move the 4 out of the summation because just a constant multiplier
4 *sum from 1 to 10 for (1/4)^(n-1) [sorry i don't know how to write sums using latex)
The formula for the geometric sum is :
First term*(1-multiplier^n)/(1-multiplier), formally
Here multiplier is 1/4
First term is (1/4)^(1-1) = 1
Thus the value of sum is which equals
We factored out 4 so its which is
This equals 5.333328247 which is 5.33 to the nearest hundredth
