Practicing Success
Which of the following interchange of signs and numbers would make the given equation correct? 12 ÷ 4 + 2 – 6 × 3 = 3 ÷ 12 + 6 × 2 – 4 |
÷ and +, 6 and 4 – and +, 6 and 4 × and ÷, 4 and 6 × and –, 4 and 6 |
÷ and +, 6 and 4 |
From option (1) 12 ÷ 4 + 2 – 6 × 3 = 3 ÷ 12 + 6 × 2 – 4 ⇒ 12 + 6 ÷ 2 – 4 × 3 = 3 + 12 ÷ 4 × 2 – 6 ⇒ 12 + 3 – 12 = 3 + 3 × 2 – 6 ⇒ 15 – 12 = 3 + 6 – 6 ⇒ 3 = 3 (L.H.S. = R.H.S.) |
