Fraction strips uses (least) common denominators, thus splitting big fraction into sum with like denominators and thus making addition possible.
Fraction strips require three major steps.
1. Firstly convert the problem with modelling as fraction strips.
2. Find the common denominator which should be least of all.
3. Now calculate the sum on new converted fractions.
For example:
[tex]\begin{aligned}\dfrac{1}{2} + \dfrac{3}{4} &= \dfrac{1}{4} + \dfrac{1}{4} + \dfrac{3}{4}\\&= \dfrac{2}{4} + \dfrac{3}{4}\\&= \dfrac{5}{4} = \: Ans.\end{aligned}[/tex]
