Here's why cooking a turkey is so hard - and how brining can help.

In this math video we will be using a real world ratio. We will interpret the given information to write a real world ratio. We will use equivalent ratios to write a proportion. We will use the concept of equivalency to identify the...

In this math video we will determine the unit rate or cost for one. We will begin by understanding that unit rate is the cost for 1. We will write an ratio using the given information. We will write a proportion to determine a second...

In this math video we will be converting measurements: inches to feet and inches to centimeters. We will solve this two part question using conversion ratios to write equivalent ratios, also known as a proportion. We will review how to...

In this math video we will learn how to use a ratio. We will be given a ratio of mass to volume. We will review how to write a ratio and how to write a proportion using equivalent ratios. We will use the given information and identify...

In this math video we will solve a four part constructed response question where we discover how to find & use unit rate. We will use equivalent ratios, proportions, Cross Product Property, and write & use an equation to solve each of...

In this math video we will find unit rate. We will be presented with a real world rate. We will understand the unit rate is per 1. We will write the rate as a ratio. We will write a proportion. We will solve for the missing unit per 1...

In this math video we will write a proportion using scale. We will be presented with a scale of a drawing to an actual dimension of a room. We will use the scale ratio to write and identify a proportion. We will understand that a...

In this math video we will find the percent (or part) of a whole. We will rewrite a word phrase to a mathematical expression. We will break the percent into smaller parts. We will find the percent of the whole to determine a specific...
