Answer:
25
Explanation:
To determine the greatest number of biscuits that Anna can make, we need to determine the ingredient that is the limiting factor, or the ingredient that will run out first.
Since Anna has 500 g of butter, 300 g of sugar, and 625 g of flour, we can calculate the number of biscuits that she can make using each ingredient as the limiting factor:
Using butter as the limiting factor: Anna has 500 g of butter, which is enough to make 16 biscuits because 500/175 = 2.86, which means that she has 2.86 times the amount of butter needed to make 16 biscuits.
Using sugar as the limiting factor: Anna has 300 g of sugar, which is enough to make 40 biscuits because 300/75 = 4, which means that she has 4 times the amount of sugar needed to make 16 biscuits.
Using flour as the limiting factor: Anna has 625 g of flour, which is enough to make 25 biscuits because 625/250 = 2.5, which means that she has 2.5 times the amount of flour needed to make 16 biscuits.
Therefore, the greatest number of biscuits that Anna can make is 25, using flour as the limiting factor.
