We note that 2 of the squares are entirely colored. This then meant that the number corresponding to the squares is 2 (increased by some fraction represented by the third square.) 2+?
We note that 2 of the 10 equally-sized pieces in the third triangle are colored. This then means that the fraction represented by the third square is $$\displaystyle{\left(\frac{{2}}{{10}}\right)}$$.
$$\displaystyle{2}+\frac{{2}}{{10}}={2}{\left(\frac{{2}}{{10}}\right)}$$
Thus the mixed number representing the squares is $$\displaystyle{2}{\left(\frac{{2}}{{10}}\right)}$$
Decimal
Next, we know that 2 tenths can also be written as 0.2 2+0.2=2.2
Thus the decimal representing the squares is 2.2
