Question

Diana uses 30 grams of coffee beans to make 48 fluid ounces of coffee. When guests come, she makes 100 fluid ounces of coffee. How many grams of coffee beans does Diana use when she has visitors

Answer 1

75 Grams

Explanation:

What is a ratio?

A ratio has two or more numbers that symbolize relation to each other. Ratios are used to compare numbers, and you can compare them using division.

The ratio of coffee beans to ounces is:

• 30: 40

The ratio we need to solve for is:

• ?: 100

To solve for '?', we can use this equation:

• 30 × 2.5 = 75

Why do we multiply by 2.5?

Well, good question! We multiply by 2.5 because in order to go from 40 to 100, we multiply the 40 by 2.5.

Therefore, Diana uses 75 grams of coffee when she has visitors.
