Answer
Step by step explanation
Here we are given 15/9 which means Divide 15 by 9.
Which is also called improper fraction since the numerator is higher than the denominator.
We can convert this improper fraction to mixed fraction by dividing.
When we divide 15 by 9, we get 1 as quotient and 6 as the remainder.
Here can reduce the fraction 6/9
We can divide fraction by 3, we get
6/9 = 2/3
Therefore, the answer is

The speed is the distance covered by an object at a particular time. The speed of the helicopter is equal to 10 kilometer/minute.
<h3>What is speed?</h3>
The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.
Given the helicopter travels 30 kilometers in 3 minute. Therefore, the speed of the helicopter is equal to,
Speed = 30 kilometer/ 3minutes = 10 kilometer/minute.
Hence, the speed of the helicopter is equal to 10 kilometer/minute.

Answer: no not less than 23
Your drawing was much more helpful and informative than your statements in words and symbols.
I see that you want to evaluate (3/2)^2 times (8/15)^2.
You could combine these two expressions into one, as follows:
3*8
( ----------- )^2
2*15
This, in turn, can be simplified by reduction:
( 4/5 )^2. Expanded, this result gives us 16/25.
Next problem
----------------------------
( 9/4 )^4 * ( 4/3 )^3
9^4 4^3
First, focus on ( ------- ) * ( ----------- )
4^4 3^3
Now reduce 4^3 / 4^4: The end result is 1/4.
Reduce 9^4 / 3^3. To do this, rewrite that 9 as (3^2), resulting in:
3^8 / 3^3. The end result is 3^5.
Putting this expression back together, we get 3^5 / 4 (answer)
