Answer:

Step-by-step explanation:

Multiplying fractions does not require that the fractions have the same denominator. Instead, the numerators are multiplied with each other and the denominators are multiplied with each other. However, the resulting fraction may not be in lowest terms so it may need to be reduced.

Reptile [31]

Answer:

Step-by-step explanation:

Given:

Annuity at time (n + 1) = 13.776

(1 + i)ⁿ = 2.476

Now,

$S_{n/i}=\frac{(1+i)^n-1}{d}$

here, d = $\frac{i}{1-i}$

thus,

$13.776=\frac{2.476-1}{d}$

d = 0.1071

therefore,

d = $\frac{i}{1+i}$

0.1071 = $\frac{i}{1+i}$

0.1071 + 0.1071i = i

i = 0.1199

now,

(1 + i)ⁿ = 2.476

(1 + 0.1199)ⁿ = 2.476

1.1199ⁿ = 2.476

taking log both sides

n × log(1.1199) = log(2.476)

n = 8.006 ≈ 8

hence,

the answer is 8
