Answer:
the duplicate ratio of a : b
= a²/b²
Step-by-step explanation:
for example:-
for understanding
if u wanna find the duplicate ratio of 4:5
so,
4²/5²= 16/25
•°• 16:25
16:25 is your duplicate ratio of 4:5

Answer:
The avocado picker earned $151.44.
Step-by-step explanation:
Given that avocado pickers are paid $ 0.10 if they collect from 1 to 500 avocados, $ 0.14 if they collect from 500 to 700 and $ 0.18 if they collect more than 700, to determine what would be the gross earnings for a worker that picks 1,108 avocados, the following calculation must be done:
1,108 - 700 = 408
700 - 500 = 200
500 x 0.10 + 200 x 0.14 + 408 x 0.18 = X
50 + 28 + 73.44 = X
151.44 = X
Therefore, the avocado picker earned $151.44.
Well I don't know !
Let's get together and work it out.
We don't know the original price yet, but we need to give it a name so that we can work with it in math equations and stuff. I'm going to call it OP.
OP was reduced by 45% before Fred came along.
That means that 45% of OP was cut off and discarded.
How much of it was left ?
Well, before it was reduced, 100% of it was marked on the price tag.
After 45% was cut off, there was (100% - 45%) = 55% of it left.
That's what Fred paid for the one he bought . . . 55% of OP.
55% of OP is $124 .
We have to change that sentence into math.
-- 55% means 0.55
-- "of" means "times"
-- "is" means 'equals sign'
So now we can write: 0.55 x OP = $124
There's the equation.
Now, divide each side
by 0.55, and you get OP = $124 / 0.55
= $225.45
