The easiest way is dividing 49 by 121 on the calculator.
Or, you can use long division and divide 49 by 121.
If you want to cheat check out my source below, it will do the work for you.

Jim burne... had the answer, but i think you should round it to the the least number of places (49 has 2, 121 has 3, so the answer would be rounded to 2 places unless otherwise commanded. so the answer would be 0.40 cm. If i didn't know for sure I would ask the teacher right before i turned it in.

Note the following pattern for repeating decimals:
0.22222222... = 2/9
0.54545454... = 54/99
0.298298298... = 298/999
Division by 9's causes the repeating pattern.
Note the pattern if zeros preceed the repeating decimal:
0.022222222... = 2/90
0.00054545454... = 54/99000
0.00298298298... = 298/99900
Adding zero's to the denominator adds zero's before the repeating decimal.
To convert a decimal that begins with a non-repeating part, such as 0.21456456456456456..., to a fraction, write it as the sum of the non-repeating part and the repeating part.
0.21 + 0.00456456456456456...
Next, convert each of these decimals to fractions. The first decimal has a divisor of power ten. The second decimal (which repeats) is convirted according to the pattern given above.
21/100 + 456/99900
Now add these fraction by expressing both with a common divisor
20979/99900 + 456/99900
and add.
21435/99900
Finally simplify it to lowest terms
1429/6660
and check on your calculator or with long division.
= 0.2145645645...
