All the properties of multiplication may be used with money.
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator.
To divide two fractions, multiply the first by the reciprocal of the second.
Dividing fractions invole multiplacation because you can use it too see how many time's a number goes into another answer. And that is why dividing involves multiplacation.
Identity property of multiplication
When comparing or simplifying fractions.

The multiplicative property, probably.
Identity property of multiplication: States that when a given number is muliplied by one (fraction that equals 1) the result equals the given number.By reducing them to their lowest terms by means of their greatest common factors.
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator.
Because you need to use inverse operations and the opposite of multiplication is division.
In what situtation can you use only multiplication to find equivalent fraction? Give an example
When the fraction is in simplest terms.
you use multiplication in math because somtimes you need it. like with fractions multiplying and adding are completely different
