The fraction 2/3 of a number is calculated by multiplying the number by 2 and then dividing the number by 3 .
Let us consider a number a.
To find 2/3 of the number a ,
we have to multiply the number by 2 = 2a
Then we have to divide the product by 3 .
Therefore 2/3 of a number will look like 2a/3 .
A number that represents a fraction of a whole is used to express fractions. Any number, amount, or portion of an object can all be regarded as a fraction.
The fractional bar is a horizontal bar that divides each fraction's numerator and denominator in half.
The numerator gives the number of selected or visible portions of the fraction. Above the fractional bar, in the upper portion of the fraction, is where it is located.

There are various types of Diophantine equations, but probably the most basic is the linear version: ax + by = c.
Different methods also abound for solving these types of equations:
- Coordinate geometry
- Modular arithmetic
- Induction

Answer:
C, The marble is 3 times as likely to be black as it is to be white.
Step-by-step explanation:
The probability of a marble being drawn is:
number of marbles of that color/total number of marbles
Find total number of marbles
5+8+4+15= 35
So the probability of drawing:
white: 5/32
polka dot: 8/32
striped: 4/32
black: 15/32
The probability of drawing white, polka dot, or striped is obviously different, so A is wrong.
The probability of drawing every color but black is 5/32 + 8/32 + 4/32 = 17/32, which is more than the chance of drawing black, so B is wrong.
The probability of drawing black is 15/32, and that is 3 times larger than the probability of drawing white (5/32), so C is correct.
The probablility of drawing a polka dot is 8/32, which is not four times as large as stripe (4/32), so D is wrong.

Answer:
x = 4
Step-by-step explanation:
Divide by 2, subtract 8 ...
2(4/x +8) = 18
4/x +8 = 9
4/x = 1
4 = x . . . . . multiply by x
