How to add, subtract, multiply and devide a fraction?

Sagot :

[tex]Just\ follow\ the\ formula\ below: \\ \\ Adding\ fractions: \\ \frac{x}{y}+\frac{x}{y}= \frac{2x}{y} \\ \\ Subtracting\ fractions: \\ \frac{2x}{y}-\frac{x}{y}= \frac{x}{y} \\ \\ ^{Remember,\ you\ could\ do\ the\ following\ formulas\ if\ you\ already\ get\ the\ GCF} \\ ^{if\ the\ following\ fractions\ are\ \underline{dissimilar\ fractions}} \\ \\ Mutiplying\ fractions: \\ \frac{x}{y}\times\frac{x}{y}= \frac{x\cdot x}{y\cdot y} [/tex]

[tex]Dividing\ fractions: \\ \\ \frac{ \frac{x}{y}}{ \frac{x}{y}}\to \frac{x}{y}\times \frac{y}{x} \to \frac{xy}{yx} \\ \\ ^{|\ Always\ do\ the\ reciprocal\ and\ change\ the\ operation\ always...} \\ \\ \\ Hope\ it\ Helps :) \\ Domini [/tex]
