Answer:
Below in bold.
Step-by-step explanation:
12.054 is about 0.9612 of 12.54.
12.054 is 12.54 - 12.054 = 0.486 less than 12.54.
First, we need to convert all the fractions to have the same denominator. 10 and 25 are both multiples of 100, so 100 would be appropriate.
Sam has a 7/25 chance. Because we want ?/100, something needs to change. To get from 25 to 100, you need to times 25 by 4, right? So, do the same with the 7.
7 x 4 = 28. Therefore Sam has a 28/100 chance.
Sue has 3/10. Using the same method, we can see that 3 needs to be multiplied by 10 (because 10 times 10 = 100). So Sue has a 30/100 chance.
Tom is already in the fraction we like, so just keep this as 21/100.
Now, add 28/100, 30/100 and 21/100 to get 79/100.
Because won of them will get the role of class president, we know that the probability adds to 1. To get a full probability (100/100, or 1), what needs to be added to 79/100?
Another way of going about this is 100/100-79/100. The answer is 21/100
The probability of Liz winning is 21/100.
Let me know if this is still unclear, I would be more than happy to explain in more detail if necessary :)
Subtract 24 to 78. Divide the answer by 24. Multiply it by 100. So the final answer is 225%.
We have a starting value of 24. In order to reach 78, we need to multiply a number to 24 and add it to 24.
Making the equation 24 + 24P = 78.
Transpose 24 to the other side, you’ll get 24P = 78--24.
24P=54.
Divide both sides by 24, you’ll get P = 2.25
Multiply 2.25 by 100 to get the percentage.
So, you’ll get the final answer 225%
You can find what 1% is of 75 by dividing 75 by 100 in a calculator, which is .75
Next you can do .75*64, which is 48.
