<p>Ancient people counted using fingers, sticks, bones, etc. As life became more complex, a standardized system like Roman Numerals was needed. The Roman Numeral system uses I (1), V (5), X (10), L (50), C (100), D (500), and M (1000). In Roman Numerals, we use MCMXCIX to represent 1999.</p>

<h3>Explanation</h3>
49
-
<p>To find the number of coins each museum receives, we divide the total number of coins by the number of museums.</p>
50
-
<p>MMMCMXCIX = 1999</p>
51
-
<p>IX = 9 Therefore,</p>
52
-
<p>MMMCMXCIX / IX = 1999 / 9 = 222.</p>
53
-
<p>222 in Roman numerals can be written as CCXXII.</p>
54

58
-
<p>The car raced for MMCDLXXXV minutes.</p>
59
-
<h3>Explanation</h3>
60
-
<p>To find the total time, multiply the number of laps by the time per lap.</p>
61
-
<p>XXXV = 35</p>
62
-
<p>LXXI = 71</p>
63
-
<p>Total minutes = 35 × 71 = 2485.</p>
