Step-by-Step Solution

To solve the equation 3b=76 3b = \frac{7}{6} for the variable b b , we will perform the following steps:

  • Step 1: Identify the equation. The given equation is 3b=76 3b = \frac{7}{6} .
  • Step 2: Isolate the variable. Divide both sides by 3 to solve for b b .

When we divide both sides of the equation by 3, we obtain:

b=763 b = \frac{\frac{7}{6}}{3}

Step 3: Simplify the expression. Dividing a fraction by an integer is equivalent to multiplying the denominator of the fraction by that integer:

b=76×3 b = \frac{7}{6 \times 3}

The denominator becomes:

b=718 b = \frac{7}{18}

Thus, the solution to the equation is b=718 b = \frac{7}{18} .

This matches the correct answer choice among the given options.

Therefore, the value of b b is b=718 b = \frac{7}{18} .

Answer

b=718 b=\frac{7}{18}
