This is a geometric sequence with first term a1 = -4 and common ratio r = 4
so nth term = a1* r^(n-1)
= -4 *4^(n-1)
Answer:
Multiply the numbers until you get the same denominator (Bottom number) for both fractions. I will do #1 to show you.
1/3 1/2
Both 3 and 2 go into 6, so I will use that.
When multiplying the bottom , you have to do the same to the top, so...
2/6 OR 3/6
3/6 is greater, so that is the answer.
Therefore, 1/2 is more
Another way you can do this is to draw a pizza, a section off parts of it according to the fractions.
Hope this helped.
