You find the LCM of the denominators in the fractions, then you multiply both fractions as needed till both have like denominators. Then you subtract.
For example:
5/9 - 2/4
LCM of 9 and 4 is 36
[(5 x 4)/(9 x 4)] - [(2 x 9) - (4 x 9)]
= 20/36 - 18/36
20/36 - 18/36 = 2/36
2/36 = 1/18
hope this helps ya!
Answer:
The amount of sales in order to meet her goal must be greater than or equal to $20,000
Step-by-step explanation:
Let
x----> represent the amount of sales Liz will need
we know that
The amount of sales for the month multiplied by the commission rate as a decimal plus the fixed amount must be greater than or equal to $2,800 each month
so
The inequality that represent this situation is
![0.03x+2,200\geq 2,800](https://tex.z-dn.net/?f=0.03x%2B2%2C200%5Cgeq%202%2C800)
solve for x
subtract 2,200 both sides
![0.03x \geq 2,800-2,200](https://tex.z-dn.net/?f=0.03x%20%5Cgeq%202%2C800-2%2C200)
![0.03x \geq 600](https://tex.z-dn.net/?f=0.03x%20%5Cgeq%20600)
divide by 0.03 both sides
![x \geq \$20,000](https://tex.z-dn.net/?f=x%20%5Cgeq%20%5C%2420%2C000)
The amount of sales in order to meet her goal must be greater than or equal to $20,000
