Well round the numbers to the nearest hundred then add.

300 + 600 = 900
800 + 400 = 1200
1200 + 900 = 2100
2100 is your sum

Step-by-step explanation:

In this problem, we need o find the rate in cups of lime juice per cup of yogurt.

It is given that, a salad dressing recipe includes 4/5 cup of lime juice for every 2 cups of Greek yogurt. Its rate is given by :

$R=\dfrac{\dfrac{4}{5}\ \text{cups of lime juice}}{2\ \text{cups}}\\\\R=\dfrac{4}{5}\times 2\\\\R=\dfrac{8}{5}\ \text{cups of lime juice per cup}$

Hence, the rate is 8/5 cups of lime juice per cup.
