Answer:
no
Step-by-step explanation:
You want to know if 320 g of margarine and 500 g of sugar are enough to make 36 brownies if the recipe for 15 brownies needs 125 g of margarine and 225 g of sugar.
Ratios
We can compare the ratios of the quantity on hand to the recipe quantity for each ingredient to the ratio of the numbers of brownies Oral wants to make. If the on-hand amount is a smaller ratio, then Orla has insufficient ingredients.
Margarine
Orla's 320 g of margarine is enough to make 320/125 = 2.56 recipes. The number of recipes Orla wants to make is 36/15 = 2.4, so she has enough margarine.
Sugar
The 500 g of sugar Orla has will make 500/225 ≈ 2.22 recipes. This is not enough for 2.4 recipes, so Orla does not have enough sugar.
