0. We need to determine:

(i) The fraction of his income spent on food.
(ii) How much he spends on rent.
(iii) The angle representing savings.

2. Solution Steps

(i) Fraction of income spent on food:
The angle for food is 120120^\circ. The total angle in a circle is 360360^\circ. Therefore, the fraction of income spent on food is given by:
120360=13 \frac{120}{360} = \frac{1}{3}
(ii) Amount spent on rent:
The angle for rent is 9090^\circ. Therefore, the fraction of income spent on rent is:
90360=14 \frac{90}{360} = \frac{1}{4}
The amount spent on rent is this fraction of the total income:
Rent=14×GH¢1,800 \text{Rent} = \frac{1}{4} \times GH¢1,800
Rent=GH¢450 \text{Rent} = GH¢450
(iii) Angle representing savings:
The angles for the different expenditures are given as:
Food: 120120^\circ
Rent: 9090^\circ
Drinks: 6060^\circ
Clothing: 5050^\circ
The sum of all angles in a circle is 360360^\circ. Let xx be the angle representing savings.
x+120+90+60+50=360 x + 120 + 90 + 60 + 50 = 360
x+320=360 x + 320 = 360
x=360320 x = 360 - 320
x=40 x = 40^\circ

3. Final Answer

(i) The fraction of Mr. Asiedu's income spent on food is 13\frac{1}{3}.
(ii) Mr. Asiedu spends GH¢450 on rent.
(iii) The angle that represents savings is 4040^\circ.
