Answers
One half is equivalent to the fraction: 1/2. Therefore, it is half of any amount. Halves are calculated by dividing by 2.
For example:
One half of 10 = ½ of 10 = 10/2 = 5.
One half of 34 = ½ of 34 = 34/2 = 17.
Three halves of 14 = 3/2 of 14 = 3 x 14/2 = 3 x 7 = 21.
Thirds
One third is equivalent to the fraction: 1/3. Therefore, it is a third of an amount. Thirds are calculated by dividing by 3.
For example:
One third of 24 =1/3 of 24 = 24/3 = 8.
One third of 33 =1/3 of 33 = 33/3 = 11.
Five thirds of 15 = 5/3 of 15 = 5 x 15/3 = 5 x 5 = 25.
Fourths
One fourth is equivalent to the fraction: 1/4. Therefore, it is a quarter of an amount. Fourths are calculated by dividing by 4.
For example:
One fourth of 20 = ¼ of 20 = 20/4 = 5.
One fourth of 28 = ¼ of 28 = 28/4 = 7.
Seven fourths of 8 = 7/4 of 8 = 7 x 8/4 = 7 x 2 = 14.
