- 5713
- You can’t tell

From the statement #1, can you tell how many people took the taste test?

- Part to whole
- Part to part
- Whole to whole

From the statement #1, can you tell how many people took the taste test?

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.

- 17,139
- 11,426

- You can’t tell

From the statement #1, can you tell how many people took the taste test?

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

From the statement #1, can you tell how many people took the taste test?

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.

- 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

Since you can not

determine the total

number surveyed, you

can not find the fraction!!!

- From statement #2 ---
- You can only look at statement #2
- What is the ratio of those that preferred Bolda Cola to those that preferred Cola Nola in simplest form? (reduced)

Since you do not know the parts

that give the difference of 5,713

you can not find the ratio!!!

- 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.

- 700 BC & 300 CN
- 600 CN & 400 BC
- 400 CN & 600 BC
- 300 BC & 700 CN

.6 x 1000 = 600

400 people preferred Cola Nola
