To convert any decimal number into a fraction simply divide it by 1 and follow it with as many zeros as there are numbers after the decimal point.
In this case we will divide 0.725 by 1000 (three digits <725> after the decimal point)
0.725÷1000 = 5/8
if for example you had 0.75 and had to convert it into fractions, you would divide it by 100 (because only two digits after the decimal point)
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.
From the computation done, it can be deduced that the fraction will be 5/24 while the percentage is 20.83%.
It should be noted that there are 24 hours in a day.
Since Miles is going to give Buddy’s Dad’s company 5 hours, then the fraction will be = 5/24
Now, we'll convert the fraction to percentage and this will be:
= 5/24 × 100
= 20.83%

Answer:
70 / 3
Step-by-step explanation:
x / 7 = 10 / 3
x = ( 10 / 3 ) x 7
= ( 10 x 7 ) / 3
x = 70 / 3
X is the amount of weeks.
Equation: 425+25x=875-15x
Solve for x:
25x+15x=875-425
40x=450
x=11.25
The answer is 11.25 weeks.
