Adam has 16.45 kg of flour he uses 6.4 kg to make hot cross buns. The remaining flour is exactly enough to make 15 batches of scones. How much flour in kg will be in each batch of scone

0.67kg

Step-by-step explanation:

To start we have to subtract the flour that he use to make hot cross buns

the remaining flour will be ...

16.45 kg - 6.4kg = 10.05kg

Now if with that flour he made 15 batches of scones we just have to divide it by that amount

10.05 / 15 = 0.67 kg

the amount of kilograms that will be per batch of scone is 0.67
