a. (i) a : b
[tex]a:b=1 \frac12:2 \frac25 \\ \\ = \frac32: \frac125 ....likened\ the\ denominator\ to\ 10\\ \\= \frac1510: \frac2410... both\ sides\ multiplied\ with\ 10 \\ \\ =15:24=5:8 [/tex]
a. (ii) b : c
[tex]b:c=0,105:0,350 ... both\ sides\ multiplied\ with\ 1000\\ \\ = 105: 350 ...... both\ sides\ devided\ with\ 35\\ \\= 3:10 [/tex]
b. Ratio of a : b : c
a : b₁ = 5 : 8
b₂ : c = 3 : 10
a : b : c = (a × b₂) : (b₁ × b₂) : (b₁ × c)
a : b : c = (5 × 3) : (8 × 3) : (5 × 10)
a : b : c = 15 : 24 : 50
c. 15 + 24 + 50 = 89
[tex]Alan = \frac1589 \times 100 \% \\ \\Alan = 0,1685 \times 100 \% \\ \\ Alan= 16,85 \% [/tex]
Question No. 5
The monthly salary of Paula = P
The monthly salary of Tom = T
P : T = 5 : 9
T = ⁹/₅ P
T = P + $3200
⁹/₅ P = P + $3200
⁹/₅ P - P = $3200
⁹/₅ P - ⁵/₅ P = $3200
⁴/₅ P = $3200
P = $3200 × ⁵/₄
P = $800 × 5
P = $4.000
Question No. 6
Deposit = $3800
Interest = 3% p.a
a. Simple interest for 4 years = Deposit × interest × time
SI = $3800 × 3% × 4
SI = $38 × 12
SI = $456
b. If SI = $171, time of Deposit = ?
$171 = $3800 × 3% × t
$171 = $114 × t
t = $171 ÷ $114
t = 1,5 ...........The time of deposit is 1,5 years
Question No. 7
The annual value of shop = $36.000
Property Tax Rate = 10%
The Amount of Property Tax = The Value × Tax Rate
The Amount of Property Tax = $36.000 × 10%
The Amount of Property Tax = $3.600
