Detailed Solution
Download Solution PDF1. ÷ మరియు -
912 ÷ 456 × 28 + 390 - 2 = 444
⇒ 2 × 28 + 390 - 2 = 444
⇒ 56 + 390 - 2 = 444
⇒ 446 - 2 = 444
⇒ 444 = 444
2. ÷ మరియు +
912 - 456 × 28 ÷ 390 + 2 = 444
⇒ 912 - 456 × 28 ÷ 390 + 2 = 444
⇒ 912 - 456 × 0.071 + 2 = 444
⇒ 912 - 32.376 + 2 = 444
⇒ 914 - 32.376 = 444
⇒ 881.624 ≠ 444
3. - మరియు +
912 + 456 × 28 - 390 ÷ 2 = 444
⇒ 912 + 456 × 28 - 195 = 444
⇒ 912 + 12768 - 195 = 444
⇒ 13680 - 195 = 444
⇒ 13485 ≠ 444
4. ÷ మరియు ×
912 - 456 ÷ 28 + 390 × 2 = 444
⇒ 912 - 456 ÷ 28 + 390 × 2 = 444
