Wei Ting says: '48 ÷ 8 × 2 = 48 ÷ 16 = 3.' What mistake did she make?
She is correct
48 ÷ 8 × 2 has no correct answer
Multiplication and division should be worked left to right, not combined first, so 48 ÷ 8 × 2 = 6 × 2 = 12 ✓
She should have added instead of dividing
When only multiplication and division appear, work from left to right: 48 ÷ 8 = 6, then 6 × 2 = 12 - not 48 ÷ 16.
