1. amanda bought 1 package of strawberries for $3. how many packages of strawberries can willie buy if he has $12?

a) 12
b) 8
c) 4

Explanation:

Step1: Analyze question 1

Given $1 = 4$ Ringgits, for $3$, we multiply.
$3\times4 = 12$

Step2: Analyze question 2

Given 1 Dinar = $3$, for 20 Dinars, we multiply.
$20\times3=60$

Step3: Analyze question 3

If 1 bag costs $3$, for $18$, we divide.
$18\div3 = 6$

Step4: Analyze question 4

The ratio of height to width is constant. Initial ratio is $\frac{4}{3}$. New height is 8. Let new width be $x$. Then $\frac{4}{3}=\frac{8}{x}$, cross - multiply gives $4x = 24$, so $x = 6$.

Step5: Analyze question 5

If 1 package costs $3$, for $12$, we divide.
$12\div3=4$

Answer:

1. b) 12
2. a) 60
3. b) 6
4. b) 6
5. c) 4
