Answer:
7. 32/80
8. 150
Step-by-step explanation:
7. fractions are part over whole, so 32 would be the part since it's only a part of the people who were surveyed, and 80 would be the whole.
8. Add all of the numbers under the "Number Who Own" section of the chart. This is the total number of people surveyed. Then to find how many would own a digital camera, you would have to put the number who own digital cameras over the total number of people surveyed.
This would be 32/160.
To find out how many would own digital cameras out of 750, you would have to cross multiply 32/160 and x/750.
160 times x = 160x
750 x 32 = 24,000
24,000 divided by 160x
150 = x
