A rational number includes fractions (3/4), integers (-2,-1,0,1,2), and whole numbers (0,1,2,3,4,5).
To convert a fraction into a decimal, you divide the numerator by the denominator. In your case, 4/33 as a decimal is 0.1212121212...etc..
Answer:
The original number was 54.5.
Step-by-step explanation:
If a number is increased by 2.8%, then it is 102.8% of it's original number.
In mathematics, "of" in virtually all cases means "multiplied by".
Therefore, we do the opposite:
1. Convert to a decimal.
102.8% = 1.028
2. Divide by the decimal.

3. Round it to the nearest tenth.
54.47 rounds to 54.5.
Answer:
if I'm not wrong the answer should be 67.
