In 2013, New York City (NYC) and Los Angeles (LA) has the highest populations of any cities in the United States. NYC’s populati

inna [77]

The population of these two cities combined in scientific notation is 11.9 x $10^{6}$

Step-by-step explanation:

1a. Population of NYC is 8.1 x $10^{6}$

1b. Population of LA is 3.8 x $10^{6}$

2.To find total population of the two cities combined,

2a. Add population of NYC and LA

Total population = NYC's population + LA's population

Total population = (8.1 x $10^{6}$ ) + (3.8 x $10^{6}$ )

2b. Take $10^{6}$ common

Total population = $10^{6}$ * (8.1 + 3.8)

Total population = $10^{6}$ * 11.9

Therefore, the population of these two cities combined in scientific notation is 11.9 x $10^{6}$

Answer:

1/2 = 3/6

1/3 = 4/12

1/5 = 2/10

1/4 = 5/20

Step-by-step explanation:

To make equivalent fractions, you need multiply by 1. A number divided by itself is 1.

1/1 * x/x = x/x = 1

1/2 = 3/6

$\frac{1}{2} * \frac{3}{3} = \frac{3}{6}$

1/3 = 4/12

$\frac{1}{3} * \frac{4}{4} = \frac{4}{12}$

1/5 = 2/10

$\frac{1}{5} * \frac{2}{2} = \frac{2}{10}$

1/4 = 5/20

$\frac{1}{4}*\frac{5}{5}=\frac{5}{20}$

Hope this helps :)

Have a great day!
