48x/49y•7y2

To simplify the expression \( \frac{48x}{49y} \cdot 7y^2 \), follow these steps:

1. Multiply the numerators: \[ 48x \cdot 7y^2 = 336xy^2 \]

2. Keep the denominator the same: The denominator is \( 49y \).

3. Combine the results: \[ \frac{336xy^2}{49y} \]

4. Simplify the expression:

   • Divide both the numerator and the denominator by \( 7y \): \[ \frac{336xy^2 \div 7y}{49y \div 7y} = \frac{48xy}{7} \]

So, the simplified form of the expression is: \[ \frac{48xy}{7} \]
