Answer:
Common ratio = 3/4
Step-by-step explanation:
The nth term of a geometric progression is given by
an = a1 . rn - 1
Where;
an = the nth term
a1 = the first term
r = common ratio
n = the number of terms in the series
Common ratio, r = the ratio of the second term to the first term
= a2 : a1
Given from the series,
a2 = 48
a1 = 64
Common ratio, r = 48 : 64
= 48/64 = 3/4
Answer:

Answer:
$0.80
Step-by-step explanation:
Find the unit rate
1 apple costs ?
1.20/6 = cost of 1 apple
1 apple = $0.20
4 apples = $0.20 * 4
4 apples = $0.80
A) you need to do 2+3=5 then divide £20 by 5 which equals 4, the ratio is 2:3 so you do 4x2 which equals 8 then you do 4x3=12. So your answer would be 8:12
