Answer:

number of servings = 1.5

Step-by-step explanation:

1 gallon = 16 Cups

cups of lemonade concentrate : lemonade servings

212 cups : 20 servings

How many servings can Mary make using 1 gallon of lemonade concentrate

Let

x = number of servings

cups of lemonade concentrate : lemonade servings

16 cups : x servings

Equate both ratios to get x

212 : 20 = 16 : x

212 / 20 = 16 / x

Cross product

212 * x = 20 * 16

212x = 320

x = 320 / 212

= 1.5094339622641

Approximately 1.5 servings

number of servings = 1.5

A model train has a scale of 1 in : 3in. if the real train is 12ft tall then how tall is the model train
Gelneren [198K]

If the ratio of a model train to a real train exists 1:3 and the real train exists 12 feet then the model train exists 3 feet long.

<h3>How to estimate the ratio of the model train?</h3>

Given that the model train contains a scale of 1: 3 and the real train exists 12 feet tall.

The ratio indicates how many times one number has another number.

A ratio exists as the relationship in quantity between two things.

It conveys the quantity of one thing in words of another.

The ratio of a model train to a real train exists at 1 inch :3 inches.

Height of model train = 12 * 1/4

Height of model train = 3 inches

Therefore, the ratio of a model train to a real train exists 1: 3 and if the real train exists 12 feet then the model train exists 3 feet long.
