So, Marco put 5/10 lb of pepperoni on the scale. The deli scale weighs meat in hundredths.
What would 5/10 be in hundredths?
The answer is, quite simply, 50/100.
Since it is weighed in hundredths, the denominator must be 100. To get a denominator of 100, we must multiply both the numerator and the denominator by 10.
