Answer:
The closest equivalent of the ratio of a to c will be:
a/c=1.680
Step-by-step explanation:
As 'a' is 63% of x
so
As 'c' is 3/8 of x
so
c=3/8
Thus, the closest equivalent of the ratio of a to c will be:
a/c = (0.63x)/(3/8x)
= 1.680
Therefore, the closest equivalent of the ratio of a to c will be:
a/c=1.680

Answer:
9765625
Step-by-step explanation:
There is a common ratio between consecutive terms , that is
r = 25 ÷ 5 = 125 ÷ 25 = 5
This indicates the sequence is geometric with n th term
= a₁
where a₁ is the first term and r the common ratio
Here a₁ = 5 and r = 5 , then
a₁₀ = 5 × = 5 × 1953125 = 9765625
