Write 18

Write as a fraction, what part of the day Tina did various activities:
a) sleep 9 hours,
b) school 6 hours,
c) television 0.5 hours and
d) studying 1.5 hours.

Correct answer:

a =  3/8
b =  1/4
c =  1/48
d =  1/16

Step-by-step explanation:

$$\begin{gathered} T=24\text{h} \\ a=\frac{9}{T}=\frac{9}{24}=\frac{3}{8}=0.375 \end{gathered}$$

$b=\frac{6}{T}=\frac{6}{24}=\frac{1}{4}=0.25$

$c=\frac{0.5}{T}=\frac{0.5}{24}=\frac{1}{48}=0.0208$

$d=\frac{1.5}{T}=\frac{1.5}{24}=\frac{1}{16}=0.0625$
