Answer:
Hi there! I'm here to help you with your question. To calculate the total time it would take Chloe to mow the whole lawn, we need to find out how long it would take her to mow 1/5 of the lawn.
Let's start by converting the fractions to decimals. 1/5 is equal to 0.2, and 1/4 is equal to 0.25.
Now, we can multiply the two fractions together to get the total time:
0.2 x 0.25 = 0.05
So, it would take Chloe 0.05 hours (or 3 minutes) to mow 1/5 of her lawn.
To find out the total time it would take her to mow the whole lawn, we can multiply the time it takes her to mow 1/5 of the lawn by the number of times she needs to mow the lawn:
0.05 x (number of times) = Total Time
Since Chloe has to mow the lawn 4 times, we can multiply the time it takes her to mow 1/5 of the lawn by 4:
0.05 x 4 = 0.2
Therefore, it would take Chloe 0.2 hours (or 12 minutes) to mow the whole lawn.
