Let 0.\(\overline{27}\) – 3.\(\overline{2}\) = x, where x is a proper fraction in the simplest form. Then the sum of the numerator and the denominator of x is:
The given table shows the use of chemicals (in litres) in three science laboratories of a school from 2002 to 2006. Study the table and answer the question that follows.
| Year | Laboratory | ||
| Biology | Physics | Chemistry | |
| 2002 | 52 | 61 | 47 |
| 2003 | 81 | 56 | 51 |
| 2004 | 67 | 49 | 57 |
| 2005 | 91 | 67 | 69 |
| 2006 | 93 | 73 | 72 |
What is the ratio of the total use of chemicals (in litres) in the Biology laboratory to the total use of chemicals (in litres) in the Chemistry laboratory from 2002 to 2006?
