simplify 1 1/2*3

Solution

simplify

1 \frac{1}{2} \cdot 3

4 \frac{1}{2}

Solution steps

1 \frac{1}{2} \cdot 3

Convert mixed numbers to improper fractions:

1 \frac{1}{2} = \frac{3}{2}

= \frac{3}{2} \cdot 3

Convert element to fraction:

3 = \frac{3}{1}

= \frac{3}{2} \cdot \frac{3}{1}

Apply the fraction rule:

\frac{a}{b} \cdot \frac{c}{d} = \frac{a \cdot c}{b \cdot d}

= \frac{3 \cdot 3}{2 \cdot 1}

Multiply the numbers:

3 \cdot 3 = 9

= \frac{9}{2 \cdot 1}

Multiply the numbers:

2 \cdot 1 = 2

= \frac{9}{2}

Convert improper fractions to mixed numbers:

\frac{9}{2} = 4 \frac{1}{2}

= 4 \frac{1}{2}

- 1 + 6 x - 8 x + 4 - 2 x

\frac{y + 2}{( y + 2 ) ^{2}} \cdot \frac{y ^{2} - 4}{y}

\frac{( x ^{2} + 2 x )}{x}

\frac{x ^{2} + 8 x + 15}{x ^{2} - 9}

\frac{67}{2}
