Common Questions
How do you find a fractional part of a number?
To find a fractional part of a number, multiply the fraction by the whole number. For example, 3/4 of 20 = (3/4) x 20 = 3 x 5 = 15. Alternatively, divide by the denominator first, then multiply by the numerator.
What does it mean for a fraction to be a part of a whole?
A fraction represents how many parts of a whole you have. The denominator tells how many equal parts the whole is divided into, and the numerator tells how many of those parts you have.
How do fractions relate to division?
Every fraction is equivalent to a division problem. The fraction a/b means a divided by b. For example, 3/4 means 3 divided by 4, which equals 0.75.
How do you find what fraction one number is of another?
To find what fraction a is of b, write the ratio a/b and simplify. For example, 6 is what fraction of 8? The answer is 6/8 = 3/4.
