1.- Multiplication of a fraction by a number.
A field is 2000 square meters. How many square meters does ¼ and 3/4 of the field have?
We divide the field into four parts and each part (1/4) will be 500 square meters. 3/4 will have 3 parts, that is, 1500 square meters.
1/4 of 2000 = 1/4 x 2000 = (1 x 2000) / 4 = 2000/4 = 500.
3/4 of 2000 = 3/4 x 2000 = (3 x 2000) / 4 = 6000/4 = 1500.
To take a fraction of a number, we multiply it by that number.
To multiply a fraction by a number, we multiply the numerator by that number.
