Homework Level 5-6 Lesson 4 - Ratio and Proportion

Pdf Summary

This document is a homework assignment for a Math Kangaroo Class focusing on level 5-6 students, specifically dealing with problems related to ratios and proportions. It includes five questions, each with a specific focus on problem-solving using ratio and proportion concepts.<br /><br />1. The first problem is about Tommy and Annika solving math problems at different rates. Annika solves more problems than Tommy, and together they solve a total of 49 problems. The answer provided indicates that Annika solves 7 more problems than Tommy.<br /><br />2. The second question involves determining the number of cats in a room in relation to the number of dogs, based on a ratio involving cat paws and dog tails. The solution reveals that the number of cats is one-sixth the number of dogs.<br /><br />3. The third problem is a scale drawing question, where a 3-meter stick is represented as 2 cm in a picture. In the same picture, a fence is depicted as 16 cm long, and students need to find the actual length of the fence. The answer is 2,400 cm or 24 meters.<br /><br />4. The fourth question involves the relative weights of a cat, a dog, a mouse, and a turnip, asking how the weights compare through a series of proportional relationships. The answer indicates that the dog is 20 times heavier than the turnip.<br /><br />5. The fifth problem requires finding the length of a rectangle given that its area is the same as another rectangle, but its width is one-third of the original rectangle's width. The answer is 270 cm.<br /><br />The answers to each problem are provided, helping students verify their calculations and understand the application of ratios and proportions in different contexts.
