P P 4 P 444
Let’s solve it using maths.
Let P be the weight of a big bag.
We know that a small bag = 4
2P + 4 P + 12=Subtract 4
f rom each side-4 -4
2P=P + 8 Subtract P f rom each side-P -P
P =8
Numeracy
When working out time difference we will use the Counting On Method. This method will always work.
Example: Find the time difference between 08 40 hrs and 11 10 hrs
