## How does a bar diagram work?

A bar diagram makes it easy to compare sets of data between different groups at a glance. The graph represents categories on one axis and a discrete value in the other. The goal is to show the relationship between the two axes. Bar charts can also show big changes in data over time.

A helpful way to solve fraction problems like this problem is to use a bar diagram. A bar is used to represent the whole. So we label it with the amount of the whole.

## What is the meaning of Bar in simplification?

We must remember the word VBODMAS in solving sums on simplification. These letters stand for vinculum, bracket, of, division, multiplication, addition and subtraction respectively.
