Exercise 8 Page 263

Rewrite the expression so that all of the numbers are fractions.

4 23

Practice makes perfect

Before we evaluate the expression, let's first rewrite the expression so that all of the numbers are fractions.

1 34* 2 23

MixedToFrac

a bc=a* c+b/c

1* 4 +3/4* 2*3+ 2/3

Multiply

4 +3/4* 6+ 2/3

7/4* 8/3

When we multiply fractions, we need to remember that the product of two fractions is equal to the product of the numerators divided by the product of the denominators. Let's find the given product!

7/4* 8/3
