it would be 22/30 and if you divide it by 2 its 11/15 so its right

it would have to be fifteenths and three fifteenths means that you haven't multiplied the top number

it's d because you make them the same denominator and then you ad them together to make 11/15

it's not a as it's literally adding 1 to 2 and 3 to 5. it's not b as you can't times 3 by 5 and add 1 to 2. it's either 11/30 or 11/15; a 50/50 chance.

it's simplified because they go into 15 and add them together

its 11/15 because i knew that 15 goes into 3 and 5 so then i did 5x3=15 3x5=15 then 1x5=5 and 2x3=6 add then together to get 11/15 and you cant simplifly

its because we get the denominators the same first then we add them up

\( \frac{11}{15} \)
its d because 1/3 + 2/5 would have to convert to 6/15 then 1/3 would convert to 5/15 then add them together and its 11/15
