Exercise 30 Page 23

Rewrite the mixed numbers as fractions. Then multiply the fractions.

6 38

Practice makes perfect

Before we find the exact product, we will make an estimate. We will round 34 up to 1 and we will round 8 12 up to 9.

3/4 * 8 12

Round to nearest integer

1* 9

Identity Property of Multiplication

9

The answer should be about 9. Now, let's find the exact product for the given multiplication. 34 * 8 12 We will start by rewriting the mixed numbers as fractions.

3/4 * 8 12

a bc=a* c+b/c

3/4 * 8* 2+1/2

Multiply

3/4 * 16+1/2

Add terms

3/4 * 17/2

Next, we multiply the numerators and the denominators.

3/4 * 17/2

Multiply fractions

3* 17/4* 2

Multiply

51/8

Finally, we write the fraction as a mixed number.

51/8
