Step-by-step explanation:
11.424242
isolate the repeating part
11+0.424242
focus on the repeating part
0.42424242
how many places till it repeats again?
2
let's say it is x
x=0.42424242
multiply by 100
100x=42.424242
subtract them
100x-x=42.42424242-0.42424242
the infinite repeats cancel and we get
99x=42
divide by 99

so
Answer:
0.15

Hwong could fill 12 packets of coffee in small boxes:
He has 10 boxes, so 10 x 12 = 120 packets total
Hwong's packets of coffee in the large boxes:
He can fit 50 packets into the boxes, so 120/50 = 2 large boxes and a remaining 20 packets of coffee
Therefore, Hwong can fit 12 packets of coffee to 1 small box and 8 packets to the other small box
