Answer 1

Step-by-step explanation:

Population in 2010 =

$2.5 \times {10}^{6}$

Population in 2019 =

$0.7 \times {10}^{7}$

Let population in 2010 be x

so, In 2019,

The number of times population will be k times.

Equation will be:

y = kx

where, y is the population in 2019.

$= > 0.7 \times {10}^{7} = k.(2.5 \times {10}^{6})$

$= > 7 \times {10}^{6} = k.(2.5 \times {10}^{6} )$

$= > \frac{14}{5} = k$

which is approximately equal to 2.8

Therefore, the population in 2019 will be 2.8 times of the population in 2010.
