Solution steps

7 \div 12 \div 3 \div 4

Follow the PEMDAS order of operations

Multiply and divide (left to right)

7 \div 12 = \frac{7}{12}

= \frac{7}{12} \div 3 \div 4

\frac{7}{12} \div 3 = \frac{7}{36}

\frac{7}{12} \div 3

Convert element to fraction:

3 = \frac{3}{1}

= \frac{7}{12} \div \frac{3}{1}

Apply the fraction rule:

\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}

= \frac{7}{12} \cdot \frac{1}{3}

Multiply fractions:

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

= \frac{7 \cdot 1}{12 \cdot 3}

Multiply the numbers:

7 \cdot 1 = 7

= \frac{7}{12 \cdot 3}

Multiply the numbers:

12 \cdot 3 = 36

= \frac{7}{36}

= \frac{7}{36} \div 4

\frac{7}{36} \div 4 = \frac{7}{144}

\frac{7}{36} \div 4

Convert element to fraction:

4 = \frac{4}{1}

= \frac{7}{36} \div \frac{4}{1}

Apply the fraction rule:

\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}

= \frac{7}{36} \cdot \frac{1}{4}

Multiply fractions:

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

= \frac{7 \cdot 1}{36 \cdot 4}

Multiply the numbers:

7 \cdot 1 = 7

= \frac{7}{36 \cdot 4}

Multiply the numbers:

36 \cdot 4 = 144

= \frac{7}{144}

= \frac{7}{144}
