The ratio is common, so you could write:
a1 * r^4 = a^5 (you do r^4 because there are 4 times you need to multiply by the ratio to get from a1 to a5)
Plug in the values:
3 * r^4 = 48
Divide by 3:
r^4 = 16
Take the fourth root of both sides:
r = 2
The common ratio is 2.
To write 0.09 as a decimal you have to divide numerator by the denominator of fraction 0.09 us not a fraction so it is a decimal already and finally we have 0.09 as a decimal equals 0.09
9/100=0.09 also
i hoped i help :)
