Subtracting Fractions: If the denominators are not the same, you must find the common denominator by finding the least common multiple (LCM). Multiplying Fractions: You can multiply both the numerators and denominators, whether they are common or not. Step—Cross Multiply (see if there are common multiples).

1. Example 1: 1/2 × 2/5. Multiply the numerators:
2. Example 2: 1/3 × 9/16. Multiply the numerators:
3. Example 3: Multiply: 4/5 x 7/6.
4. Example 4: Multiply: 9/4 x 14/15.
5. Example 5: Multiply (1/2) × (2/3) × (3/4) × (4/5).
6. Example 6: Multiply:3/5 × 60.
7. Example 7: Multiply: 2 5/6 x 3 1/4
8. Example 8: Multiply: 2/3 × (–3/4)

The first step when multiplying fractions is to multiply the two numerators. The second step is to multiply the two denominators. Finally, simplify the new fractions. The fractions can also be simplified before multiplying by factoring out common factors in the numerator and denominator.

There are 3 simple steps to multiply fractions

1. Multiply the top numbers (the numerators).
2. Multiply the bottom numbers (the denominators).
3. Simplify the fraction if needed.

Multiply the numerators and multiply the denominators. Simplify, if possible. This fraction is already in lowest terms. If the resulting product needs to be simplified to lowest terms, divide the numerator and denominator by common factors.

No, you cannot cross multiply when adding fractions. Cross multiply only when you need to determine if one fraction is greater than another, or if you are trying to find a missing numerator or denominator in equivalent fractions.

To find the missing denominator, first look at the numerators of the fractions. One fraction has both a numerator and denominator. Find the number that this numerator is multiplied by to get to the numerator that is missing its denominator. Multiply the known denominator by this number to find the unknown denominator.
