Answer: as a ratio it’s 140:210 and as a simplified fraction it’s 2/3. But not simplified it’s still 140/210
Step-by-step explanation:
Applying the percentages, and considering that 70% of the first group drinks at least 2 glasses of water a day, it is found that 0.725 = 72.5% of the team drinks at least 2 glasses of water a day.
The team is divided into two equal groups, hence, each represents 50%.
The <em>percentages </em>associated with drinking at least 2 glasses of water a day is:
- 70% of 50%(first group)
- 75% of 50%(second group)
Hence, applying the weighed percentage, the total percentage is:

0.725 = 72.5% of the team drinks at least 2 glasses of water a day.

A fact family is basically just different equations with the same numbers getting the same/different numbers as answers you might say...
this will make more sense:
5x8=40
8x5=40
40/8=5
40/5=8
The addition of the row and column shows that the number of people polled will be 166.
<h3>How to calculate the number?</h3>
From the information given, the guest thing to do is to add the column. This will be:
= 48 + 118 = 166
Also, it's important to add the row. This will be:
= 69 + 97 = 166
Therefore, the number of people polled will be 166.
