y:7=218*7

To solve the equation \( y:7 = 218 \times 7 \), we'll first calculate the right side:

1. Calculate \( 218 \times 7 \): \[ 218 \times 7 = 1526 \]

2. Now substitute back into the equation: \[ y : 7 = 1526 \]

3. To solve for \( y \), multiply both sides by 7: \[ y = 1526 \times 7 \] \[ y = 10682 \]

Therefore, the solution is: \[ y = 10682 \]
