Test: Measurement - Year 7 MCQ

To convert kilometres to metres, multiply by 1,000. Thus, 150 km × 1,000 = 150,000 m. This conversion is crucial for understanding vast distances in more manageable units.

One litre is equivalent to 1,000 millilitres (mL). This conversion is crucial in cooking and chemical applications where precise liquid measurements are required.

First, add the centimetres: 56 cm + 78 cm = 134 cm, which converts to 1 m 34 cm. Then add the metres: 9 m + 13 m + 1 m = 23 m. Thus, the total is 23 m 34 cm. This method emphasizes the importance of organizing measurements correctly.

Dividing 2,350 mL by 1,000 gives 2 L with a remainder of 350 mL. Therefore, the answer is 2 L 350 mL. This method demonstrates how to handle conversions effectively.

To convert metres to centimetres, you multiply the number of metres by 100. Therefore, 5 m × 100 = 500 cm. This conversion is vital for everyday situations where precise measurements are needed.

First, add the millilitres: 215 mL + 380 mL + 79 mL = 674 mL. Then add the litres: 3 L + 4 L + 6 L = 13 L. Thus, the total is 13 L 674 mL. This addition demonstrates proper column arrangement in calculations.

Convert litres to millilitres: (5 × 1,000) + 250 = 5,250 mL. This highlights the importance of accurate conversions in liquid measurements.

First, convert to centimetres: (4 × 100) + 33 = 433 cm. Then multiply: 433 cm × 5 = 2,165 cm, which converts to 21 m 65 cm. This shows the importance of conversion in multiplication.

First, add the millilitres: 500 mL + 250 mL = 750 mL. Then add the litres: 2 L + 3 L = 5 L. Thus, the total is 5 L 750 mL. This addition is a practical example of handling capacity measurements accurately.

Convert kilometres to metres: 1 km = 1,000 m, so 1,000 m + 250 m = 1,250 m. This demonstrates the necessity of understanding unit conversions in distance measurements.

To convert kilograms to grams, multiply by 1,000. Thus, 3 kg × 1,000 = 3,000 g. This conversion is essential in many real-life scenarios, including cooking, where precise weight measurements are necessary.

The basic unit for measuring length is the metre (m). It serves as the standard measurement from which other units like centimetres and kilometres are derived. Understanding this is essential for accurately measuring various objects and distances.

To convert metres to kilometres, divide by 1,000. Dividing 9,734 m by 1,000 gives 9 km with a remainder of 734 m. This process is essential for understanding larger distances.

A finger width is approximately 1 cm. This estimation technique is useful for quick assessments before taking precise measurements. Understanding how to estimate can make initial assessments easier.

Convert to grams first: (12 × 1,000) + 500 = 12,500 g. Then divide: 12,500 g ÷ 4 = 3,125 g, which converts to 3 kg 125 g. This calculation emphasizes the importance of conversion for division.
