Write $\frac{99}{100}\cdot(0.\overline{4} )$ as a fully simplified fraction.
Please help

Step-by-step explanation:

Let's rewrite as a fraction:

Let x = 0.4444444.....

10x = 4.444444....

9x = 4.44444.... - 0.44444....

9x = 4

x = 4/9

Now we can multiply the two fractions regularly

We can simplify the product :

The final answer is

-Chetan K

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
