(2*15sin(30))/(10)

\frac{2 \cdot 15 sin ( 3 0 ^{\circ} )}{10}

\frac{3}{2}

Decimal Notation

1.5

Solution steps

\frac{2 \cdot 15 sin ( 3 0 ^{\circ} )}{10}

Use the following trivial identity:

sin (3 0^{\circ}) = \frac{1}{2}

sin (3 0^{\circ})

sin (x)

= \frac{1}{2}

= \frac{2 \cdot 15 \cdot \frac{1}{2}}{10}

Simplify

\frac{2 \cdot 15 \cdot \frac{1}{2}}{10} : \frac{3}{2}

\frac{2 \cdot 15 \cdot \frac{1}{2}}{10}

Multiply the numbers:

2 \cdot 15 = 30

= \frac{30 \cdot \frac{1}{2}}{10}

Multiply

30 \cdot \frac{1}{2} : 15

30 \cdot \frac{1}{2}

Multiply fractions:

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

= \frac{1 \cdot 30}{2}

Multiply the numbers:

1 \cdot 30 = 30

= \frac{30}{2}

Divide the numbers:

\frac{30}{2} = 15

= 15

= \frac{15}{10}

Cancel the common factor:

5

= \frac{3}{2}

= \frac{3}{2}
