Question

Emma has 18 yellow flowers and 27 white flowers she wants to split them into vases in equal groupes what is the largest number of groups she can make

Answer 1

It’s 18

If they have to be equal, every vase has to have a yellow flower therefore if you had 1 yellow flower and 1 white flower (the lowest possible equal combination) then you can only have 18 groups otherwise you would have an equal number in each case
