# How Many Cookies in Total with 3 Cookies on Each of 5 Trays?

When it comes to baking, understanding quantities and measurements is crucial. Whether you’re a professional baker or a home cook, you’ve likely encountered a situation where you need to calculate the total number of cookies or other baked goods you’ve made. This article will explore a simple mathematical problem: “If Harper puts 3 cookies on each tray and there are 5 trays, how many cookies are there in total?” This question may seem straightforward, but it’s a great opportunity to delve into the concept of multiplication and its practical applications in everyday life, such as baking.

## Understanding the Problem

The problem involves two quantities: the number of cookies on each tray (3) and the number of trays (5). To find the total number of cookies, we need to multiply these two numbers together. This is because each tray contains the same number of cookies, so we can simply add the number of cookies on each tray together as many times as there are trays. This is essentially what multiplication is: repeated addition.

## Applying Multiplication

So, if we have 3 cookies on each tray and there are 5 trays, we can calculate the total number of cookies by multiplying 3 (cookies per tray) by 5 (number of trays). This gives us:
