The video tutorial explains how to determine the mass of one large brick given that six small bricks have the same mass as five large bricks. It starts by calculating the total mass of the small bricks, which is 15 kilograms, and then divides this by five to find the mass of one large brick, which is 3 kilograms. The tutorial emphasizes the importance of understanding the method and using times tables for calculations.

If six small bricks balance with five large bricks, and each small brick weighs 2.5 kg, what is the total mass of the small bricks?

• 10 kg

• 20 kg

• 15 kg

• 12.5 kg

How do you calculate the total mass of six small bricks, each weighing 2.5 kg?

• Divide 2.5 by 6

• Multiply 2.5 by 6

• Multiply 2.5 by 5

• Add 2.5 six times

What is the total mass of the five large bricks if they balance with six small bricks?

• 18 kg

• 15 kg

• 20 kg

• 12 kg

How do you find the mass of one large brick if the total mass of five large bricks is 15 kg?

• Multiply 15 by 5

• Divide 15 by 5

• Subtract 5 from 15

• Add 15 and 5

What is the mass of one large brick?

• 2 kg

• 2.5 kg

• 3 kg

• 3.5 kg
