to write decimal as a percent, multiply by 100
so 0.78 *100 = 78%
Answer:
4/6
Step-by-step explanation:
We need to find the probability of picked out each color. The are 4 red, 7 white, and 3 blue marbles. There are 14 marbles total.
So there are 4 red marbles out of the 14 marbles total. As fraction it is which simplifies to . To convert to a decimal, divide 2 by 7 to get about 0.2857. To convert a decimal to a percent, move the decimal point 2 spaces down to get 28.57%
There are 7 white marbles out of 14 marbles total. As fraction it is which simplifies to . This is 0.5 or 50%.
There are 3 blue marbles out of 14 marbles total. As fraction it is which can't simplify. Divide 3 by 14 to get the decimal which is about 0.2143. Move the decimal 2 spaces down (basically dividing it by 100) to get 21.43%.
Answer:
The first step is to determine how many times 2x goes into 8x^3
Step-by-step explanation:
The first step is to determine how many times 2x goes into 8x^3
4x^2
--------------------------
2x-1 | (8x3 – x2 + 6x + 7
8x^3 -4x^2
