First, write each factor in expanded form. Then, draw your model. Next, multiply to find the area of each smaller rectangle. Finally, add those products to find the total area.

What is an example of an area model?

Even larger products can be found using the area model. For example, 356 × 48 can be found by writing 356 as 300 + 50 + 6 and 48 as 40 + 8 (again, retaining the feature that each term has only a single non-zero digit), then finding the areas of the six regions.

How is dividing with an area model similar to multiplying with an area model How is it different?

It is similar to an area model for multiplication. You can think of division as finding a missing factor. The dividend is the product, the divisor is the known factor, and the quotient is the unknown factor. The area model shows 345 4 15.

What is the general rule for multiplying fractions?

Multiply Straight Across. The first, and most important, rule of multiplying fractions is that you only multiply numerator × numerator and denominator × denominator. If you have the two fractions 2/3 and 4/5, multiplying them together would create the new fraction: (2 × 4) / (3 × 5)

How do you do multiplying fractions?

To multiply fractions: Simplify the fractions if not in lowest terms. Multiply the numerators of the fractions to get the new numerator. Multiply the denominators of the fractions to get the new denominator.

How do you solve a multiplication fraction?

Multiplying Fractions Calculator. Instructions. Name. Multiply Value. Fraction multiplication instructions: Press the New Problem button or fill in the empty fields (Fraction One and Fraction Two). Next fill in the Your Answer field with your answer to the problem. Press the Multiply button to see if your answer is correct.

How is dividing fractions different from multiplying fractions?

To multiply fractions, all you have to do is multiply the numerators and denominators and simplify the result. To divide fractions, you simply have to flip the numerator and denominator of one of the fractions, multiply the result by the other fraction, and simplify. 4 is the largest number that is evenly divisible by both the numerator and the denominator of this fraction, so divide each by 4 to get the simplified answer.
