Answer:
Final temeprature = 29 - 29 = 0c
Step-by-step explanation:
The key to solving this problem is in the statement "the average temperature had fallen by 29c"
This means that the average temperature had reduced by a value of 29c from the initial value, hence we will subtract 29 from the initial temperature
Initial temperature = temperature in July = 29c
in order to find the final temperature, we will subtract 29c from the initial temperature:
Final temperature (temperature in December) = 29 - 29 = 0c
Two ways of solving:
1. Convert the fractions to decimals:
3/7 = 0.42857
3/5 = 0.6
0.42857 < 0.6
So 3/7 < 3/5
Second way is to rewrite the fractions with a common denominator:
3/7 = 15/35
3/5 = 21/35
Now compare the numerators:
15 < 21 so 3/7 < 3/5
