Question

7. The diagram below shows how much time Antoine spends doing different activities each day. How many hours does Antoine SLEEP in a day? (HINT: There are 24 hours in 1 day) btw 2.4 is not the answer I just clicked it on accident

Answer 1

Percentage

We know that the 100% of the diagram correspond to 24 hours. We can see that Antoine sleeps 40% of the day. We want to know what is the 40% of 24h.

We have the following equivalence:

40% ⇄ ?

100% ⇄ 24h

If we divide both sides of the equivalence we will have the same result

`\begin{gathered} (40)/(100)=(?)/(24) \\ (2)/(5)=(?)/(24) \end{gathered}`

if we multiply both sides if the equation by 24:

`\begin{gathered} (2)/(5)=(?)/(24) \\ 24\cdot(2)/(5)=\text{?} \\ (48)/(5)=\text{?} \\ 9.6=\text{?} \end{gathered}`

Answer: Antoine sleeps 9.6 hours
