Question

Sara bought 230 g of sugar and 520 g of salt. What is their total weight in kg?

• A.
  1 kg
• B. $\frac{3}{4}$ kg
• C. $\frac{1}{3}$ kg
• D. $\frac{1}{2}$ kg

Answer 1

The correct option is B $\frac{3}{4}$ kg

Weight of sugar = 230 g
Weight of salt = 520 g
Total weight = 230 g + 520 g = 750 g

Since we know that 1 kg = 1000 g,
$\frac{1}{4}$ kg = 1000 $÷$ 4 = 250 g
750 g = 250 g $\times$ 3 = $\frac{1}{4}$ kg $\times$ 3 = $\frac{3}{4}$ kg
