Answer: 23/45
step-by-step explanation:
write out your equation equal to x
x = 0.51 with a repeating 1
count the repeating decimal (1) and multiply each sides of the equation by 10^1
10x = 5.11 with a repeating 1
9x = 4.6 subtract the first equation from the second
solve for x
x = 4.6/9
eliminate the 1 decimals by multiplying the numerator and denominator by 10^1
4.6/9 • 10/10 = 46/90
find the greatest common factor
46/2 / 90/2 = 23/45
the fraction is already simplified at 23/45
i hope this helps :)
Answer:
24
Step-by-step explanation:
Let 12x represent the original number.
One fourth of that number can be represented by 3x, and one third of the number can be represented by 4x.
Create an equation that sets this equal to 38, and solve for x:
12x + 3x + 4x = 38
19x = 38
x = 2
The original number is represented by 12x, so plug in 2 as x:
12(2)
= 24
So, the original number is 24.

The formula for volume of a cylinder is 3.14r^2h.
r = 3
h = 6
3.14 x 3^2 x 6
3.14 x 9 x 6
=169.56
