Question

The circumfrence of a ball is 60cm. The ball rolls 16.2m. How many times does the ball make one complete roll? 

Answer 1

$1 roll=circumference$

$\frac{distance}{circumference} =rolls$

$\frac{16.2m}{60cm} =rolls$

$\frac{(16.2*100)cm}{60cm} =rolls$

$\frac{1620cm}{60cm} =rolls$

$27 = rolls$

$27times$
