Hi. Okay, #16 says write a decimal between 0.5 and 0.75. Then write it as a fraction in simplest form and as a percent.
write a decimal = I will pick 0.15 - now we need to write it as a fraction since the 5 is in the hundredths place our fractions would be:
15/100 = 3/20 (simplest form)
Now to change .15 to a percent we simply move the decimal two places to the right and add a % sign so. 15 = 15%
Question 17
How would you write 43 3/4% as a decimal
For this one, it is a lot easier than you think. The answer is 43.75. Let me tell you how...
To change 3/4 to a decimal, you are merely dividing the 4 into 3.00, hence the .75 and then just bring the 43 over. With problem like this that end in 1/4, 1/2, 3/4 just think of 4 quarters---1 quarter =.24, 2 quarters = .50, 3 quarters =.75
Question 16 answer is: .15, 15/100=3/20 and 15%
Question 17 answer is: 43.75
I hope this helps. If you have any questions, please don't hesitate to ask.
Take care,

<h3>Solving word problems involving ratios.</h3>
The solution to the word problem involving ratios in the given problem can be determined as follows.
From the given information:
The total number of people in the hospital = male + female
= 184 + x(unknown)
- If the ratio of male to female is 4: 3.
- The total ratio is 4+3 = 7
The ratio of males in the hospital is:
x = 322
The number of female patients in the hospital can now be computed as:
= 138 female patients
Check:
The total number of people in the hospital is:
= 184 + 138
= 322 patients

you need to be consistant when setting up the proportions. The times always need to be on top and the days needs to always on bottom.
Cross multiply and solve for the variable.
20(30) = 5(m)
600 = 5m
120 = m
So, in 30 days the theatre showed 120 movies.
