You can multiply the numerator and the denominator by 4, as shown in part B above. But you cannot multiply the numerator by 4 and the denominator by 2. The numerator and the denominator of a fraction must be multiplied by the same nonzero whole number in order to have equivalent fractions.You may be wondering why this is so.xample 4. Multiplying the numerator and the denominator of a fraction by the same nonzero whole number will change that fraction into an equivalent fraction, but it will not change its value. Equivalent fractions may look different, but they have the same value. Let's look at some more examples of equivalent fractions.
When the percent is less than or equal to 100%, then we can say out of 100. 25% is 25 out of 100. But 250% cannot mean 250 out of 100 -- that makes no sense. It means 250 for each 100, which is two and a half times.t is not obvious how to make 28 into 100. But 7 is the fourth part, or a quarter, of 28. And as a percent, a quarter of a number is 25%. 7 is 25% of 28.
