Whenever multiplying a fraction by an integer (in this case, the 100), my students are told to put the integer over a 1 so that they will see whether the numerator or denominator gets multiplied by the integer. (After getting used to it, the 1 becomes unnecessary.) Here is what they would do: 4/30 x 100/1 Multiply straight across, numerator by numerator and denominator by denominator (the 4 times the 100 and the 30 times the 1). You get 400 on top and 30 on the bottom. 400/30 Then you reduce the fraction by dividing BOTH the top and the bottom by the SAME number that will go into each of them. In this case, they can both be divided by 10. You get 40/3. Since another number can't go into BOTH of them at the same time, it is reduced.
