1,5 . n = 13,65

We know:

$1,5=\frac{15}{10}$

and

$13,65=\frac{1365}{100}$

So,

$\frac{15}{10}.n=\frac{1365}{100}$

Pass $\frac{15}{10}$ as division.

$n = \frac{\frac{1365}{100}}{\frac{15}{10}}$

Btw, we also know:

$\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a.d}{b.c}$

So,

$n = \frac{\frac{1365}{100}}{\frac{15}{10}}$

$n = \frac{1365.10}{100.15}$

$n = \frac{13650}{1500}$

$n = \frac{91}{10}$

$n = 9,1$

zmey [24]

Answer:

(a) 6.2843 billion

(b) 6.8716 billion

Step-by-step explanation:

Since there is a constant growth rate of 1.5% per year, and the population in 2002 was 6.1 billion people. The general equation for the total world population, in billions, after 2002 is:

$P(t) = 6.1*(1+0.015)^t$

With t being the time, in years, after 2002.

a) What was the population in 2004?

$t=2004-2002=2\\P(2) = 6.1*(1.015)^2\\P(2) = 6.2843 \ billion$

b) What was the population in 2010?

$t=2010-2002=8\\P(8) = 6.1*(1.015)^8\\P(8) = 6.8716 \ billion$
