Problem 1.1 -

How many people took the taste test?
• 17,139
• 11,426
• 28,565
• 5713
• You can’t tell
A ratio is what kind of comparison?
• Part to whole
• Part to part
• Whole to whole

A ratio is a part to part comparison.

Since Bolda comes first in the statement and 17,139 is the first number in the statement, 17,139 people preferred Bolda Cola.

How many people preferred Cola Nola?
• 17,139
• 11,426
• 28,565
• You can’t tell

A ratio is a part to part comparison.

Since Bolda comes first in the statement and 17,139 is the first number in the ratio, 17,139 people preferred Bolda Cola.

That means 11,426 people preferred Cola Nola

Bolda

+ Nola

= Total

17,139

+ 11,426

= 28,565

28,565 total people took the survey

What percent of the people surveyed preferred Bolda Cola?

The information is given as a ratio. A ratio is a part to part comparison.

A percent is what kind of a comparison?
• Part to part
• Part to whole
• Whole to whole

What percent of the people surveyed preferred Bolda Cola?

The information is given as a ratio. A ratio is a part to part comparison.

A percent is a is a part to whole comparison.

If 17,139 and 11,426 are the 2 parts, what is the whole?

17,139

+ 11,426

= 28,565

28,565 total people took the survey

is what percent?
• 50%
• 60%
• 70%
• 80%
• Not given

REMEMBER, 28,565 total people took the survey

A fraction is what kind of a comparison?
• Part to part
• Part to whole
• Whole to whole

28,565 total people took the survey

• Those who like Bolda Cola
• Those who like Cola Nola
• Those who like Dr. Pepper

What fractional part of the people surveyed preferred Cola Nola?

• Yes
• No

If you change the data in #1 into the ratio of those that preferred Bolda to those that preferred Nola, the reduced form would be

• The same as #4.
• Yes, the difference in statement #2 is the same as the difference in # 1
• If you change the data in #1 into the percent that preferred Bolda, the answer is 60%, the same as #3

#1 = #2; #1 = #3; & #1 = #4

Therefore all of the statements COULD have come from the same data.
