We have a total of 10 boys & 8 Girls, then the sample space consist of 18 elements.
P(selecting 1 boy) = (total number of boys/by 18) = P(boy)=10/18=5/9
It is (c+d)
you can basically use FOIL (first,outside,inside,last) to solve this.
you know the first term of the factor has to be C because of the c^2
the second then has to be D because you haven't seen D in the factor yet and it is in the equation.
then you know from the equation that the terms with D are not negative so D isn't negative so you have form the information above (c+d)
To compare fraction sizes, you have to make sure the denominators of the fractions are the same. You must find a number that is a multiple of all the denominators we currently have (15, 3, 12, 9)
The smallest number that fits this is 540
Now you must multiply the numerator and denominator of each fraction by the number that makes the denominator 540
So, for 7/15 , we multiply the top and bottom by 36, since you need to multiply 15 by 36 to get 540. This means the fraction you end up with is 252/540
For 2/3, we multiply the top and bottom by 180, since you need to multiply 3 by 180 to get 540.This means the fraction you end up with is 360/540
For 11/12, we multiply the top and bottom by 45, since you need to multiply 12 by 45 to get 540. This means that the fraction you end up with is 495/540
For 5/9, we must multiply the top and bottom by 60, since you need to multiply 9 by 60 to get 540. This means that the fraction you end up with is 300/540
Now that the hard part is out of the way, you have four fractions: 252/540, 360/540, 495/540 and 300/540. Now, you can arrange the fractions in ascending order just based on their numerator.
So, the order would be: 252/540, 300/540, 360/540, 495/540
Now, for the final step, just convert them back to the original fractions.
So, the final answer is:
7/15, 5/9, 2/3, 11/12
Hope I helped!! xx
Answer: The ratio of protein bars to water bottles will be 4:3.
Explanation:
Since we have given that
Number of protein bars = 20
Number of water bottles = 15
We need to calculate the ratio of protein bars to water bottles which is given by
So, the ratio of protein bars to water bottles will be 4:3.
