The calculator will show you the product of the two fractions, including the negative sign if applicable.

You can also use the calculator to multiply positive fractions by entering positive numbers.

How Negative Fraction Multiplication Works

When multiplying two negative fractions, you multiply the numerators together and the denominators together, then simplify the result if possible. The negative signs multiply to give a positive result.

(-a/b) × (-c/d) = (a × c)/(b × d)

For example, multiplying -3/4 by -2/5 gives:

(-3/4) × (-2/5) = (3 × 2)/(4 × 5) = 6/20 = 3/10

The negative signs cancel out, resulting in a positive fraction.

Worked Examples

Example 1: Multiplying -1/2 by -3/4

Using the formula:

(-1/2) × (-3/4) = (1 × 3)/(2 × 4) = 3/8

The result is 3/8.

Example 2: Multiplying -5/6 by -7/8

Using the formula:

(-5/6) × (-7/8) = (5 × 7)/(6 × 8) = 35/48

The result is 35/48.

Example 3: Multiplying -2/3 by -4/5

Using the formula:

(-2/3) × (-4/5) = (2 × 4)/(3 × 5) = 8/15

The result is 8/15.

Frequently Asked Questions

What happens when you multiply two negative fractions?

Multiplying two negative fractions results in a positive fraction. The negative signs cancel each other out.

Do you need to simplify the result after multiplying fractions?

Yes, you should simplify the resulting fraction by dividing both the numerator and denominator by their greatest common divisor (GCD).

Can you multiply a negative fraction by a positive fraction?

Yes, the result will be a negative fraction. The negative sign from the negative fraction will remain in the result.

What is the formula for multiplying two fractions?

The formula is (a/b) × (c/d) = (a × c)/(b × d). For negative fractions, the negative signs are handled separately.
