Flying Fungi

Let’s imagine that we tested the air in your classroom and found 7 different kinds of mould. Eek! The cleaner says that it takes 5 days for each mould to be eradicated (removed). If the school had to remove each mould one at a time, how long would it take to remove all the mould from the classroom?


On your blog, tell us how you would solve this tricky maths problem. Be sure to also post your final answer in days or weeks.

I managed to solve it. 5 x 7 = 35

It is because there are 7 different kinds of mould and it would takes 5 days for each moulds to be removed for 35 days.
