Alyssa's ratio of correct questions to total questions is 16 : 20. 16 divided by 20 = 0.80 x 100% = 80%, Alyssa got a B on her quiz.
In order to get an A on the exam, Alyssa needs a ratio of 90 : 100. Looking at the solutions in part (a), 100 is 5 times 20 so to see how many questions Alyssa needs to answer correctly out of 20 we can divide 90 by 5. Since 90 ÷ 5 = 18, Alyssa needs to answer 18 questions correctly. The ratios 18 : 20 and and 90 : 100 are equivalent since both numbers are scaled by the same factor, 5, to get from the first pair of numbers to the second.
Jessie answered 3 times as many questions correctly than she did incorrectly. This means that for every 1 question Jessie answered incorrectly, she answered 3 questions correctly. In other words, Jessie's ratio of correct answers to incorrect answers is 3 : 1.
If the letter z's are distinctly different, there are P(5,5) arrangements. That is
![P\left(5,5\right)=5!=5\cdot 4\cdot 3\cdot 2\cdot 1=120](https://tex.z-dn.net/?f=P%5Cleft%285%2C5%5Cright%29%3D5%21%3D5%5Ccdot%204%5Ccdot%203%5Ccdot%202%5Ccdot%201%3D120)
If the z's are interchangeable, the number of different arrangements is given by

3/4 divided by 1/8 equals
The Correct Answer is 6
Step-by-step explanation:
Dividing two fractions is the same as multiplying the first fraction by the reciprocal (invers
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomese) of the second fraction.
3/4 x 8/1 which equals 24/4
and 24/4 Equals 6
therefore, 3/4 divided by 1/8 Equals 6
