Practice makes perfect

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

2 14 * 2/3

a bc=a* c+b/c

2* 4 + 1/4 * 2/3

Multiply

8+1/4* 2/3

Add terms

9/4* 2/3

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!

9/4* 2/3

Multiply fractions

9* 2/4 * 3

Rewrite 9 as 3 3

3 * 3* 2/4 * 3

Rewrite 4 as 2 * 2

3 * 3* 2/2 * 2 * 3

Cancel out common factors

3 * 3* 2/2 * 2 * 3

Simplify quotient

3/2

Now, let's simplify the result!
