Question

Find the number that makes the equation true.
$7.80/hour = ____ cents/minute

Answer 1

Write the conversion as fractions:\[$7.80 /h * 1 h/60 m * 1 m / 60 s * 100 cents/1 $=\]All the units cancel out, leaving cents/second. If the units don't cancel properly, your conversion won't be correct, either.
