Answer:
A): 22/5 = 4 2/5 in mixed fraction. 22/5 = 4.4 in decimal. B): 0.875
Step-by-step explanation:
Since you can't divide 7/8 it will turn into decimal. If you use calculator, it will be decimal. Basically in order to do long division, you would need to drop down zeros like add zeros if the divisor and dividend don't equal. You keep adding zeros until it's equal. IF it is more likely to be continuous, then you would need to add a repetend on the last digit. For example, 3/1 you can know it would be 1.333333 and so on. Example of how to do it:
The probability of picking red button is
<u>Solution:</u>
Given, A jar contains 30 red, 30 blue, and 60 white buttons.
You pick one button at a random choice,
We have to find the probability that it is red button.
Now, total number of buttons = 30 + 30 + 60 = 120 buttons.
Number of favourable cases for red button = 30 red buttons.
The probability of an event is given as:
Thus the probability that it is red is
