Irene owns a bakery. for each cake, she spends 1/4 of an hour to make frosting and 2/5 hour to decorate. how many cakes can irene bake in 3 1/4 hours?

The answer is 5 cakes.

EXPLANATION

To solve this, you work out that 1/4 of an hour is 15 mins 2/5 of an hour is 24 mins and that 3 1/4 hours is 195 mins.

Using these, we can work out that it takes 39 mins per cake (15 for frosting + 24 for decorating). When we divide 195 by this we get 5, meaning that the answer is 5 cakes.

Hope this helps!
