Step-by-Step Solution

To solve the equation 4x=18 4x = \frac{1}{8} , we need to isolate x x . We do this by dividing both sides of the equation by the coefficient of x x , which is 4:

  • Step 1: Write the original equation: 4x=18 4x = \frac{1}{8} .
  • Step 2: Divide both sides by 4 to solve for x x :

x=184 x = \frac{\frac{1}{8}}{4}

  • Step 3: Simplify the right-hand side by multiplying fractions, recalling that dividing by a number is equivalent to multiplying by its reciprocal:

x=18×14=1×18×4=132 x = \frac{1}{8} \times \frac{1}{4} = \frac{1 \times 1}{8 \times 4} = \frac{1}{32}

Thus, the solution to the equation is x=132 x = \frac{1}{32} .

Answer

132 \frac{1}{32}
