Which statements describes 3/8 * 4/9 with groups of 8 or 3

Hi there!

Well to solve this problem we obviously need to multiply 3/8 by 4/9,

3/8*4/9=12/72

3 groups of 4/9 bascially means 3*4/9

3*4/9=12/9

Divide by 8,

12/9/8=12/9*1/8=12/72

Thus, As I divided into 3 groups of 4/9 which is 3/9*4/8

Hoped I helped. :)

Step-by-step explanation:

Given that:

Investment amount = $2500

Time in which it gets doubled = 15 years

Amount after 15 years = $5000 (As per given statement as it gets doubled)

Value of investment in dollars after years if investment:

is a constant.

To find:

Value of .

Solution:

We are given that:

Putting all the values in the given equation:

Therefore, the value of is:
