1?4 of 30,000 voted for the Blue Party. So, 30,000 ÷ 4 = 7,500. That means 30,000 - 7,500 voted for other parties. 30,000 - 7,500 = 22,500

If the denominators (bottom numbers) are the same, you can subtract by simply subtracting their numerators (top numbers). 15?11 ? 7?11 = 8?11

If 12?16 of the class like football, then 4?16 of the class do not like football because 12 + 4 = 16: this can be simplified to 1?4 by dividing by 4
|
If the denominators (bottom numbers) are the same, you can add by simply adding their numerators (top numbers). 9?21 + 5?21 = 14?21 BUT this can be reduced to 2?3 if you divide the denominator and the numerator by the SAME number, in this case 7

Numbers followed by th, st or rd (as in, fourth, first or third) are known as ordinal numbers. The denominators (bottom numbers) in fractions are almost always ordinal numbers

There are nine ninths in 1. If you have eaten 2?9, there can only be 7?9 left because 2 + 7 = 9: if the denominators are the same, you can add/subtract the fractions by simply adding/subtracting their numerators
|
All the other fractions can be reduced to 1?6 which is smaller than 7?28 or 1?4

The three wrong answers can be reduced to 1?3 which is greater than 9?36 or 1?4

If you divide the denominator and the numerator by the SAME number, you can reduce the fraction to its simplest form. In this case, you divide the denominator AND the numerator by 3
