[(62.25/2.5) + (12.5/0.5)] / [(0.75 * 9) + (3.5 * 3.5)]
= [(6225/250) + (125/5)] / (6.75 + 12.25)
= (249/10 + 25) / 19 = 499/190 = 2 119/190

 Discuss Question
Answer: Option C. -> 12 25/224
7 + 5 – (3/2 * 1/4) OF 2/7 + 7/2 * 1/16
= 7 + 5 – (3/2 * 1/4) * 2/7 + 7/2 * 1/16 = 7 + 5 – 3/28 + 7/32
= 12 + 3/28 + 7/32 = 12 + (7 * 7 – 3 * 8)/224
= 12 + 25/224 = 12 25/224

Answer: Option C. -> 0.3
0.003 * ? * 0.0003 = 0.00000027
3/1000 * ? * 3/10000 = 3/1000 * 3/1000 * 3/100
? = 3/10 = 0.3

Answer: Option B. -> 150 2/3
6 2/3 * 9 3/5 * 2 1/3 + 1 1/3 = 20/3 * 48/5 * 7/3 + 4/3
= 448/3 + 4/3 = 452/3 = 150 2/3
Question 1456. [(7 * 9) + (2 * 12) + 3]/[(12 * 3) + (81/9)] = ______?

Answer: Option C. -> 9000
9000 + 16 2/3 % OF ? = 10500 => 9000 + 50/3 % OF ? = 10500
50/(3 * 100) OF ? = 1500 => ? = 1500 * 6
? = 9000
Question 1458. 60 + 5 * 12 / (180/3) = _______?
  1.    60
  2.    120
  3.    13
  4.    61
 Discuss Question
Answer: Option D. -> 61
60 + 5 * 12 / (180/3) = 60 + 5 * 12 / (60)
