Solution steps

30 \div 100 \times 120

Follow the PEMDAS order of operations

Multiply and divide (left to right)

30 \div 100 = \frac{30}{100}

= \frac{30}{100} \times 120

\frac{30}{100} \times 120 = 36

\frac{30}{100} \cdot 120

Cancel

\frac{30}{100} : \frac{3}{10}

\frac{30}{100}

Factor the number:

30 = 10 \cdot 3

= \frac{10 \cdot 3}{100}

Factor the number:

100 = 10 \cdot 10

= \frac{10 \cdot 3}{10 \cdot 10}

Cancel the common factor:

10

= \frac{3}{10}

= \frac{3}{10} \cdot 120

\frac{3}{10} \cdot 120 = 36

\frac{3}{10} \cdot 120

Convert element to fraction:

120 = \frac{120}{1}

= \frac{3}{10} \cdot \frac{120}{1}

Apply the fraction rule:

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

= \frac{3 \cdot 120}{10 \cdot 1}

Cancel

\frac{3 \cdot 120}{10 \cdot 1} : 36

\frac{3 \cdot 120}{10 \cdot 1}

Multiply the numbers:

10 \cdot 1 = 10

= \frac{3 \cdot 120}{10}

Divide the numbers:

\frac{120}{10} = 12

= 3 \cdot 12

Multiply the numbers:

3 \cdot 12 = 36

= 36

= 36

= 36

= 36
