2 1/4 ⋅ 1 2/3<br> as a mixed number

Gemiola [76]

Answer:

$3\frac{3}{4}$

Step-by-step explanation:

We have two mixed numbers and are asked to multiply them together.

2 1/4 * 1 2/3

First we convert the mixed numbers into improper fractions to make it easier for us. So follow the MA rule.

Multiply the whole number by the denominator and add the numerator.

2 1/4 * 1 2/3

9/4 * 5/3

Now multiply across,

$\frac{9*5}{4*3}$

$\frac{45}{12}$

Now we need to convert this back into a mixed number.

So how many times does 45 go into 12?

3 times, and 3 are left.

$3\frac{3}{4}$
