3 3/8= </span>(3/1) + (3/8)=
= (3x8)/8 + (3/8)
=(3x8 +3) / 8 putting both numbers with the same denominator
=27/8
27 is the same as 3³ 3x3x3= 27
8 is the same as 2³ 2x2x2= 8
= 3³÷ 2³
2)
1 11/25= (1/1) + (11/25)
= (25/25) + (11/25) putting both numbers with the same denominator
= (25+11)/25
=36/25
36 is the same as 6² 6x6=36
25 is the same as 5² 5x5=25
6²/5²
Answer:
-4
Step-by-step explanation:
The average rate of change of a function f(x) between two points x = a and x=b is given by,

This can be understood with a simpler example, the straight line.
In this case, the rate of change of the 'function' is given by the slope,
;
being two points on the straight line.
So, for the given problem,
a = -2
b = 2
Hence, average rate of change of 
You are basically just comparing the ratios (the ratios will have to be the same for both for it to be the correct answer)
so for choice A you would do:
116.5cm:845km =0.14
174cm:1160km=0.15
these are not equal so it would not be correct
the correct answer would be B because:
42.25cm:845km=.05
58cm:1160km=.05
