alexandr1967 [171]

Answer:

The answer for part A: If the city is hotter in temperature more people will want the cold refreshing lemonade.

Step-by-step explanation:

Part A: Because if it is hot outside you will sweat more being less hydrated which is why more people would want a drink especially lemonade.

What's bigger 9/10 or 4/5
ch4aika [34]
To be able to compare 2 fraciton we have to make common denominator and then we can just compare numerators. 
\frac{4}{5}= \frac{4*2}{5*2}= \frac{8}{10}
Now we can compare numerator from the first (9) and from the second fraction (8)
9>8, so the bigger is 9/10
