1 \div 2 \div 3 \div 7

\frac{1}{42}

Solution steps

1 \div 2 \div 3 \div 7

Follow the PEMDAS order of operations

Multiply and divide (left to right)

1 \div 2 = \frac{1}{2}

= \frac{1}{2} \div 3 \div 7

\frac{1}{2} \div 3 = \frac{1}{6}

\frac{1}{2} \div 3

Convert element to fraction:

3 = \frac{3}{1}

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

Apply the fraction rule:

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

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

Multiply fractions:

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

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

Multiply the numbers:

1 \cdot 1 = 1

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

Multiply the numbers:

2 \cdot 3 = 6

= \frac{1}{6}

= \frac{1}{6} \div 7

\frac{1}{6} \div 7 = \frac{1}{42}

\frac{1}{6} \div 7

Convert element to fraction:

7 = \frac{7}{1}

= \frac{1}{6} \div \frac{7}{1}

Apply the fraction rule:

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

= \frac{1}{6} \cdot \frac{1}{7}

Multiply fractions:

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

= \frac{1 \cdot 1}{6 \cdot 7}

Multiply the numbers:

1 \cdot 1 = 1

= \frac{1}{6 \cdot 7}

Multiply the numbers:

6 \cdot 7 = 42

= \frac{1}{42}

= \frac{1}{42}

(25 + 3) (35 + 3)

5^{3} \cdot 2^{3}
