<h3>Hello!</h3>
Option A is correct & here's why.
When dividing fractions, we take the first fraction and multiply it times the reciprocal of the second fraction (the second fraction flopped over)
So if we have 1/4, then its reciprocal is 4/1, or just 4.
Hence, Option A (1/5÷4) is correct.

Part A: Let the September price be x, then
1.2x = 1.5
x = 1.5/1.2 = 1.25
Therefore, September price is $1.25
Part B: In September, they earned 0.4 * 1.25 * 900 = $450
In October, they earned 0.4 * 1.5 * 700 = $420
Therefore, they earned more money in September.
7.5 = x +
equals
x = 6.
First, subtract
from both sides. / Your problem should look like: 7.5 -
= x.
Second, simplify 7.5 -
to 6. / Your problem should look like: 6 = x.
Third, switch sides. / Your problem should look like x = 6, which is your answer.
Answer:
720 beans in total
Step-by-step explanation:
I would set this up with proportions, so-
1 180
4 x
Then cross multiply-
4 x 180 = 720
Divide-
720/1 = 720
720 is your answer
