Sure. With this question, you're looking for the better deal, i.e. how many yogurts you can get for the least amount of money spent. With the first one, we know that 18 of them cost 12,99 euros and the other promotion has 4 yogurts for 2,70 euros.
Can you think of how you might go about getting in a position for each where you have the price per 1 yogurt?
so you can compare and contrast

Close, it's the other way around. Think of them like fractions: 18y/12,99 vs 4y/2,70
divide the top and bottom of each by their respective numerators and write them down, see what you get
you'll get the amount that a single yogurt would cost for each deal
yup, that's right
now that you know that, it's just a matter of saying that one deal is better than the other due to having a lower cost per single yogurt
You're welcome, good luck with the rest of your homework and studies in general
