Explanation:

Activity 1 Step1: Compare numerators (same denominator)

Fractions: $\frac{1}{9}, \frac{2}{9}, \frac{4}{9}, \frac{5}{9}, \frac{9}{9}$

Activity 2 Step1: Find LCM of 4 and 12

$\text{LCM}(4,12)=12$; Multiples: $12, 24$

Activity 2 Step2: Find LCM of 3 and 12

$\text{LCM}(3,12)=12$; Multiples: $12, 24$

Activity 2 Step3: Find LCM of 2 and 20

$\text{LCM}(2,20)=20$; Multiples: $20, 40, 60$

Activity 2 Step4: Find LCM of 4 and 6

$\text{LCM}(4,6)=12$; Multiples: $12, 24, 36, 48$

Answer:

Activity 1 (least to greatest):

$\frac{1}{9}$, $\frac{2}{9}$, $\frac{4}{9}$, $\frac{5}{9}$, $\frac{9}{9}$

Activity 2:

1. $12$, $24$
2. $12$, $24$
3. $20$, $40$, $60$
4. $12$, $24$, $36$, $48$
