Question 11 of 20intermediate🔧 ApplyNumerical3 marks

Which is heavier: 1215\frac{12}{15} of 500 grams or 320\frac{3}{20} of 4 kg?

Correct Answer

Step 1: Calculate 1215\frac{12}{15} of 500 g 1215×500=45×500=400\frac{12}{15} \times 500 = \frac{4}{5} \times 500 = 400 g

Step 2: Calculate 320\frac{3}{20} of 4 kg 4 kg = 4000 g 320×4000=600\frac{3}{20} \times 4000 = 600 g

Step 3: Compare 600 g > 400 g

Answer: 320\frac{3}{20} of 4 kg (600 grams) is heavier than 1215\frac{12}{15} of 500 grams (400 grams).

Explanation

The chapter explains multiplication of fractions to find parts of quantities. 1215×500=45×500=400\frac{12}{15} \times 500 = \frac{4}{5} \times 500 = 400 grams. 320×4000=600\frac{3}{20} \times 4000 = 600 grams. 600 grams > 400 grams.

Solution Steps

  1. Step 1: Calculate 1215\frac{12}{15} of 500 g: 1215×500=45×500=400\frac{12}{15} \times 500 = \frac{4}{5} \times 500 = 400 g

  2. Step 2: Calculate 320\frac{3}{20} of 4 kg: 4 kg = 4000 g

  3. Step 3: 320×4000=600\frac{3}{20} \times 4000 = 600 g

  4. Step 4: Compare: 600 g > 400 g
