1/64. ÷ 1/27
1/64 × 27/1
= 27/64
Solutions
1) <span>Lets use n as alex's number
</span>⇒ n x 1000
⇒ n ÷ 10
⇒ = 475
To solve the problem do the opposite steps
475 ÷ 1000 = n
n = <span>0.475
</span>
0.475 x 10 = n
n = 4.75
CHECK YOUR WORK
4.75 x 1000 = 4750
4750 ÷ 10 = 475
The answer is correct
⇒ The answer Alex is thinking of is 4.75

Answer:
First dimension= 12ft Second dimension= 12×2.5=30ft
Step-by-step explanation:
From the question, I was able to deduce that the swimming pool is a cuboid, and the formula for finding the volume of a cuboid is Length×Breadth×Height.
let the first dimension be the length and the second dimension be the breadth.
Therefore, the length=L , Breadth= 2.5×L= 2.5L and Height= 8ft. L×2.5L×8 = 2880 cubic feet.
2.5L²×8= 2880 cubic feet. Therefore, L²= 2880/(2.5×8)=144. L²=144. L=√144. L=12ft. and breadth= 2.5×Length= 2.5×12ft=30ft.
In a nutshell the first dimension is 12ft, and the second is 30ft.
