A salad dressing is 30% peanut oil. Rosie Wants To Make 3 CUPS OF DRESSING. How much peanut oil does she need?

0.3 * 3 = 0.9 cups

0.30*3=0.9cups

To calculate the amount of peanut oil Rosie needs for her dressing, you'll first need to determine the amount of dressing she wants to make (3 cups) and the percentage of peanut oil in the dressing (30%).

To find the amount of peanut oil required, you can use the following formula:

Amount of peanut oil = (Percentage of peanut oil / 100) * Amount of dressing

Let's substitute the values into the formula:

Amount of peanut oil = (30 / 100) * 3 cups

Now, calculate the expression:

Amount of peanut oil = 0.3 * 3 cups

Hence, Rosie will need 0.9 cups of peanut oil for her dressing.

30% of 3 cups!
