write -49/10 as a dessimal
To write -49/10 as a decimal, we divide -49 by 10:
-49 ÷ 10 = -4.9
Therefore, -49/10 as a decimal is -4.9.
wire 0.555555as a fraction
To write 0.555555 as a fraction, we can set x = 0.555555 and multiply both sides by 10^n, where n is the number of decimal places:
10^n * x = 10^n * 0.555555
10^n * x = 5.5555555...
Next, we subtract x from 10^n * x:
10^n * x - x = 5.5555555... - 0.555555
Simplifying the right side:
10^n * x - x = 5
Factoring out x:
x(10^n - 1) = 5
Dividing both sides by (10^n - 1):
x = 5 / (10^n - 1)
To determine the fraction, we need to find the appropriate value for n. Since there are six repeating decimals, n = 6:
x = 5 / (10^6 - 1)
x = 5 / (1,000,000 - 1)
x = 5 / 999,999
Hence, 0.555555 as a fraction is approximately 5/999,999.
whats the anwser
The answer is approximately 5/999,999.
what is 2/3 of the dessimal
To find 2/3 of a decimal, you can multiply the decimal by 2/3.
Let's say the decimal is represented by x.
2/3 of x = (2/3) * x
For example, if the decimal is 0.75:
2/3 of 0.75 = (2/3) * 0.75 = 0.5
So, 2/3 of the decimal 0.75 is 0.5.
