Answer

\( k = \frac{16}{21} \)

Solution

To solve for \( k \) in the equation: \[ \frac{3k}{8} = \frac{2}{7} \] follow these steps: ### Step 1: Eliminate the Denominator Multiply both sides of the equation by 8 to eliminate the denominator on the left side: \[ 8 \times \frac{3k}{8} = 8 \times \frac{2}{7} \] This simplifies to: \[ 3k = \frac{16}{7} \] ### Step 2: Solve for \( k \) Now, divide both sides of the equation by 3 to isolate \( k \): \[ k = \frac{16}{7} \div 3 \] Dividing by 3 is the same as multiplying by \( \frac{1}{3} \): \[ k = \frac{16}{7} \times \frac{1}{3} = \frac{16}{21} \] ### Final Answer \[ k = \frac{16}{21} \]

Mind Expander

To solve for \( k \), you need to multiply both sides of the equation by the reciprocal of \( \frac{3}{8} \), which is \( \frac{8}{3} \). Starting with the equation \( \frac{3k}{8} = \frac{2}{7} \), multiply both sides by \( \frac{8}{3} \): \[ k = \frac{2}{7} \times \frac{8}{3} \] Simplifying this gives: \[ k = \frac{16}{21} \] Therefore, the solution is \( k = \frac{16}{21} \).
