GCSE Maths - Simplifying Harder Ratios (Decimals, Mixed Units and 1:n) - Part 2 #82

This video tutorial covers advanced examples of simplifying ratios, including those with decimals, mixed units, and converting ratios to the form 1:N. It explains how to handle decimals by multiplying to remove them, converting units to simplify ratios, and adjusting ratios to achieve a 1:N form. The tutorial provides step-by-step instructions and examples for each type of ratio simplification.

What is the first step in simplifying a ratio with decimals, such as 1.5 to 4.5?

• Subtract 10 from both sides

• Add 10 to both sides

• Multiply both sides by 10

• Divide both sides by 10

After converting 1.6 centimeters to millimeters, what is the next step in simplifying the ratio 1.6 cm to 12 mm?

• Divide both sides by 4

• Multiply both sides by 4

• Add 4 to both sides

• Subtract 4 from both sides

When simplifying a ratio with mixed units, why is it generally easier to convert to the smaller unit?

• To simplify the addition

• To make the numbers larger

• To avoid decimals

• To increase the ratio

How do you simplify the ratio 50 minutes to 1.5 hours?

• Convert hours to seconds

• Convert minutes to hours

• Convert hours to minutes

• Convert minutes to seconds

What is the goal when adjusting a ratio so that one side becomes 1?

• To express the ratio in terms of one unit

• To make both sides equal

• To simplify the ratio to a fraction

• To make calculations easier

In the ratio 3 to 20, what operation is needed to make the left side equal to 1?

• Divide by 3

• Multiply by 3

• Add 3

• Subtract 3

What is the resulting ratio when you simplify 5 to 20 to the form N to 1?

• 1 to 0.5

• 1 to 0.25

• 0.25 to 1

• 0.5 to 1
