Aim

To be able to find a missing value in a ratio.

Introduction

We are using the skills we learned last week to find missing values in a ratio.

Each number in a ratio can be divided or multiplied by a number and the result will be equivalent.

We can chain divisions, and / or multiplications, and the resulting ratio is still equivalent, provided we do the same thing to each number in the ratio.

Task

All questions on worksheet.
