Select the correct combination of mathematical signs that can sequentially replace the * signs and make the equation correct. 45 * 24 * 72 * 20 * 12 * 7 |
×, ÷, =, –, + ÷, ×, +, –, = =, ×, +, ÷, – +, ÷, –, =, × |
×, ÷, =, –, + |
From the option (1) 45 × 24 ÷ 72 = 20 – 12 + 7 ⇒ 45 × \(\frac{24}{72}\) = 8 + 7 ⇒ 15 = 15 |
