i think this because the common denominator of 3 and 5 is 15 so you would do 5/15 + 6/15, which is 11/15.

\( \frac{1}{3}+\frac{2}{5}= \)
\( \frac{11}{15} \)
i think this because the denominator are not equal so you change it to the lowest number the two denominator it go into. that is 15 so since 3x5 (the two denominators) equal 15 you times 5 and 1 and 3 and 2 which is 5/15 + 6/15 = 11/15

i think this because the denominator is 15 then you do 1 times 5 and then 2 times 3 then add them and the answer is 11/15

i think this because the denominators are both factors of 15, and i multiplied the numerators and denominators into however much they go into 15

\( \frac{1}{3}+\frac{2}{5}= \)
\( \frac{11}{15} \)
i think this because the denominators are not same so you would have to make the denominators same. the denominators will be 15 and the fractions would be 5/15 + 6/15 which is = 11/15.

\( \frac{11}{15} \)
i think this because the domoninator is x by 5 so the top need to be x by 5 with gives 5/15 and the other one is x by 3 so its 6/15 them added together is 11/15

\( \frac{1}{3}+\frac{2}{5}= \)
\( \frac{11}{15} \)
i think this because the lcm of 3 and 5 = 15, so we change the denominators to 15. the answers to this would be 5/15 + 6/15 which is 11/15.

\( \frac{1}{3}+\frac{2}{5}= \)
\( \frac{11}{15} \)
i think this because the lcm of 3 and 5 is 15, therefore, i would make my denominator 15 and then multiply the numerators accordingly to these- 5/15 + 6/15= 11/15.

\( \frac{1}{3}+\frac{2}{5}= \)
\( \frac{11}{15} \)
i think this because the lowest common denominator is 15 and that means you have to make them both into 15 ths. so 1/3 becomes 5/15 and 2/5 becomes 6/15 and 6+5=11 so it would be 11/15.

\( \frac{1}{3}+\frac{2}{5}= \)
\( \frac{11}{15} \)
i think this because the lowest common denominator is 15 so 15 goes into to 5 3 times therefore 3x2=6 . in addition, 15 goes into 3 5 times so 5x1=5 and 5+6=11
