Solution

The correct option is B 14

$= (4 \div \frac{2}{7}) m$

$Calculating 4 \div \frac{2}{7} using the k e e p - c h a n g e - f l i p method, we get:$

$Calculating 4 \times \frac{7}{2}, we get:$

$4 \times \frac{7}{2} = \frac{4 \times 7}{1 \times 2} = \frac{28}{2} = 14$

$∴ The total number of steps on the$ $ladder is 14 .$
