Step-by-step explanation:
hello :
the n-ieme term is : An=A1×r^(n-1)
A1 the first term r : the common ratio
in this exercice : A1 =15 r = 1/3 n = 4
A4=15×(1/3)^(4) =15×4^4 =3840
Answer: 45%
Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. If we want to write 9/20 as a percent, we will need to find a fraction equivalent to 9/20 that has a 100 in the denominator. We can do this by setting up a proportion.
=
Now, we can use cross products to find the missing value.
900 = 20n
÷20 ÷20 ← divide by 20 on both sides
45 = n
Therefore, 9/20 is equal to 45 over 100 or 45%.

Answer: 0.45
Step-by-step explanation: In order to write 9/20 as a decimal, we need to find a fraction equivalent to 9/20 with a 100 in the denominator. Notice that if we multiply both the numerator of 9/20 by 5, we get the equivalent fraction 45/100 which we can now write as a decimal. Remember that the hundredths place is two places to the right of the decimal point. So, we can write 45/100 as 0.45.
Therefore, 9/20 is equivalent to 0.45.
The required, 9/20 as a decimal is 0.45, and as a percentage is 45%.
Decimals and percentages are both ways to express numbers that are less than or equal to 1. Decimals are a way to represent numbers using the base-10 numbering system. Percentages, on the other hand, are a way to express a portion of a whole as a fraction of 100.
To convert 9/20 to a decimal, divide the numerator (9) by the denominator (20).
9 ÷ 20 = 0.45
So, 9/20 as a decimal is 0.45.
To convert 0.45 to a percentage, multiply it by 100.
0.45 x 100 = 45
So, 9/20 as a percentage is 45%.
In summary, 9/20 as a decimal is 0.45, and as a percentage is 45%.
