No, you cannot use models to multiply fractions!!
You multiply the fractions
No. Fractions don't need the same denominator in order to multiply them. The numerator of their product is simply the product of their numerators, and the denominator of their product is just the product of their denominators.
No! You can multiply fractions without common denominators. For example: 2/4 + 7/1 Multiply straight across. The answer is then 14/4 or 3.5

When you add or subtract fractions you cross multiply and when you multiply or divide fractions you across multiply.
