Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Start with the given equation.
  • Step 2: Use cross-multiplication to eliminate the fractions.
  • Step 3: Simplify the resulting expression.
  • Step 4: Solve for the variable a a .

Now, let's work through each step:
Step 1: The equation given is a6=67 \frac{a}{6} = \frac{6}{7} .
Step 2: We apply cross-multiplication: Multiply both sides to get a×7=6×6 a \times 7 = 6 \times 6 .
Step 3: Simplify the equation: 7a=36 7a = 36 .
Step 4: Solve for a a by dividing both sides by 7:
a=367 a = \frac{36}{7} .
This fraction can be converted to a mixed number: a=517 a = 5\frac{1}{7} .

Therefore, the solution to the problem is a=517 a = 5\frac{1}{7} .

Answer

a=517 a=5\frac{1}{7}
