Ratio problems

Introduction for practice ratio problems:

In mathematics, a ratio expresses the magnitude of quantitie relative to each other. Specifically, the ratio of two quantities also indicates how many times the first quantity is contained in the second and may be expressed algebraically as their quotient. Example: For every Spoons of sugar, you need 2 spoons of flour (1:2)

In our daily life, by studying ratio and proportion many a times we compare two quantities of the same type. Thus, in convinced situation, comparison by division makes better sense than comparison by taking the difference. This could also help us on angle of inclination. The comparison by division is the Ratio. We denote ratio-using symbol ‘:’ . This could also help us on Introduction to proper fraction. If two ratios are equal, we state that they are in proportions and use the symbol ‘:’ or ‘=’ to equate the two ratios.
