Dividing Quantities in Ratios

The video tutorial explains how to divide a quantity into a given ratio, using a step-by-step approach. It begins by identifying the total number of parts in the ratio, then calculates the size of each part. The tutorial demonstrates the process with an example, dividing 270 kilos into a 4:5 ratio, resulting in parts of 120 and 150 kilos. The instructor emphasizes the importance of understanding each step to avoid common mistakes and provides a review of the process for clarity.

What is the first step in dividing a quantity into a given ratio?

• Calculate the size of each part

• Multiply the ratio by the total quantity

• Determine the total number of parts

• Divide the total quantity by the ratio

If a ratio is 4:5, how many total parts are there?

• 4

• 5

• 9

• 10

How do you calculate the size of each part when dividing 270 kilos into 9 parts?

• Multiply 270 by 9

• Divide 270 by 9

• Add 270 to 9

• Subtract 9 from 270

What is the size of each part when 270 kilos is divided into 9 parts?

• 30 kilos

• 25 kilos

• 35 kilos

• 20 kilos

In a 4:5 ratio, how many kilos correspond to the '4 parts' when each part is 30 kilos?

• 180 kilos

• 150 kilos

• 90 kilos

• 120 kilos

In a 4:5 ratio, how many kilos correspond to the '5 parts' when each part is 30 kilos?

• 130 kilos

• 150 kilos

• 120 kilos

• 140 kilos

What is the final division of 270 kilos in a 4:5 ratio?

• 110 kilos and 160 kilos

• 130 kilos and 140 kilos

• 120 kilos and 150 kilos

• 100 kilos and 170 kilos

What is the importance of setting out the steps clearly when dividing quantities?

• To confuse others

• To save time

• To ensure understanding of the process

• To make it look neat

If a ratio is 1:6, how many total parts are there?

• 8

• 7

• 6

• 5

What should you always do after calculating the parts in a ratio?

• Add them together

• Ignore them

• Subtract them

• Check your calculations
