How do I get the answer for 1 1/2 x 3 x 1 1/9

Mekhanik [1.2K]

$\boxed{1 \frac{1}{2}\times 3 \times 1 \frac{1}{9}=5}$

<h2>Explanation:</h2>

in this problem we have the following expression:

$1 \frac{1}{2}\times 3 \times 1 \frac{1}{9}$

So here:

$1 \frac{1}{2} \ and \ 1 \frac{1}{9} \ are \ written \ as \ mixed \ fractions$

Let's convert them as improper fractions:

$1 \frac{1}{2}=1+\frac{1}{2}=\frac{1\times 2+1}{2}=\frac{3}{2} \\ \\ 1 \frac{1}{9}=1+\frac{1}{9}=\frac{1\times9 +1}{9}=\frac{10}{9}$

Rewriting our expression:

$\frac{3}{2}\times 3 \times \frac{10}{9}=\frac{3\times 3 \times 10}{2\times 9}=\frac{90}{18}=5$
