5 2/3 gave to her 4 friends how much did each one receive
Olin [163]

Answer:

Let's see what to do buddy...

Step-by-step explanation:

If it is 5 + 2/3

_________________________________

Step (1)

First we have to find all she has :

5 \frac{2}{3} = 5 +  \frac{2}{3} =  \frac{5 \times 3}{3} +  \frac{2}{3} = \\   \frac{15}{3} +  \frac{2}{3} =  \frac{17}{3}

_________________________________

Step (2)

To find how much did each of them receive , we must divided all by the number of her friends which is 4.

So we have :

\frac{17}{3} \div 4 =  \frac{17}{3} \times  \frac{1}{4} =  \frac{17}{12} \\

So each of her friends receive 17/12 .

If it is 5 × 2/3

_________________________________

Step (1)

Firs we have to find all she has :

5 \times  \frac{2}{3} =  \frac{10}{3} \\

_________________________________

Step (2)

To find how much did each of them receive , we must divided all by the number of her friends which is 4.

So we have :

\frac{10}{3} \div 4 =  \frac{10}{3} \times  \frac{1}{4} =  \frac{10}{12} \\

So each of her friends receive 10/12 .

_________________________________

And we're done.

Thanks for watching buddy good luck.

Compare the doubling times found with the approximate and exact doubling time formulas. Then use the exact doubling time formula
g100num [7]

The population after 15 years become according to the doubling time is 470000000.

According to the statement

We have given that the nation of 200 million people is growing at a rate of 9% per year.And we have to find that the What will its population be in 15 years.

So, For this purpose, we know that the

The doubling time is the time it takes for a population to double in size/value. It is applied to population growth etc.

So,

Population of nation is 200 million and growing at a rate of 9% per year.

So, 9% of the population is

Percentage population = 9/100*200,000,000

Percentage population = 9* 200,000,0

Percentage population = 1800,000,0.

It means 18000000 number of population is increased per year.

So, The total population increased in 15 years is  15*18000000

The total population increased in 15 years is  270000000.

The population after 15 years is 270000000 + 200,000,000

The population after 15 years is 470000000.

So, The population after 15 years become according to the doubling time is 470000000.
