In order to find all of these, you first must convert the percentage to a decimal. This would be 13% to 0.13.

Now, multiply 0.13 by all of these into a calculator.

1800 • 0.13 = 234
950 • 0.13 = 123.50
2200 • 0.13 = 286
3000 • 0.13 = 390
2600 • 0.13 = 338

Answer:

a. $\bold{45000\times \:10^7}$
b. $\bold{3500}$

Step-by-step explanation:

a. $\left(5\times \:10^3\right)\left(9\times \:10^7\right)$

$5\times 10^3 = 5000\\\\5000\times \:9\times \:10^7$

$\mathrm{Multiply\:the\:numbers:}\:5000\times \:9=45000$

$=45000\times \:10^7$

b. $\left(7\times 10^5\right)\div \left(2\times 10^2\right)$

$\left(7\times 10^5\right)\div \left(2\times 10^2\right)=\frac{7\times \:10^5}{2\times \:10^2}$

$\frac{10^5}{10^2} = 10^3$

$\frac{7\times \:10^3}{2}$

$\mathrm{Factor}\:\: 10^3 : 2^3\times5^3$

$\frac{7\times \:2^3\times \:5^3}{2}$

$\frac{2^3}{2}=2^2$

$7\times \:2^2\times \:5^3=3500$
