Step-by-step explanation:
A mathematical symbol, or combination of symbols, representing a value, or relation. Example: 2+2=4 .
Answer:
OPTION C: 
pounds.
Step-by-step explanation:
From the figure we can see that there are three dots against 
.
That means it becomes 
.
Note that if there is a mixed fraction of the form 
= 
.
Therefore, 
... (1)
Similarly, against 4 there are 2 dots.
So, it should be 
pounds. ...(2)
3 dots against 
.
So, it becomes 
...(3)
Similarly, 2 dots against 
.
This will become 
...(4)
Now, to calculate the total pound, we simply add (1), (2), (3) & (4).
⇒ 
+
⇒ 
⇒ 
⇒ 
which is the required answer.
