first we need to find a common denominator

[tex] \frac{2}{10} [/tex]=[tex] \frac{20}{100} [/tex]
now we can add them

[tex] \frac{20}{100} [/tex]+[tex] \frac{9}{100} [/tex]=[tex] \frac{29}{100} [/tex]

convert 2/10 to 20/100 then add 20/100+9/100 to get you answer of 29/100 also written as .29


i converted 2/10 to 20/100 by multiplying the numerator and denominator by ten
