step by step
To add fractions.
You use fractions for LOTS of things in the real world like money, gambling, shopping, clothing, etc.
Whenever we are dealing with rational fractions.
Use the GCF to reduce fractions. Use the LCM to add and subtract unlike fractions. Carpenters work with fractions a lot.
The question presumes that math classes are not part of the real world, which is debatable. The GCF can be used to simplify fractions. Carpenters and chefs use fractions in practical, non-academic settings.
You may not literally say "multiplied by a half" but multiplying and dividing by fractions are equivalents to doing the other function with an inverse number, most easily in that dividing by 2 is the same as multiplying by (1/2). We don't often multiply and divide by fractions because most of the time we can convert such a problem into a nicer one. We may use fractions like this, for example, in a test out of 90 marks where one must score 2/3 to pass. This pass mark is obtained by multiplying 90 by (2/3), though this, as said earlier, would usually, even unconsciously with such convenient numbers, be split into "divide by 3, then multiply by 2".
Fractions aren't really difficult, once you understand them. Mainly, you have to memorize when to use which operation, so that you don't get adding and multiplying fractions confused, for example.
When we simplify fractions.
you use multiplication in math because somtimes you need it. like with fractions multiplying and adding are completely different
fractions are used in the English system of mesurement (inches, feet, pounds, etc.)
