Claire mowed 7 lawns last week. she mowed each lawn in 7/12 hour. she mowed the same lawns this week in 5/12 hour. how many times longer was claires time to mow all the lawns last week than this week?

14/12 or 1.17hours longer

Step-by-step explanation:

Previous week, Claire mowed 7 lawns

Each lawn was mowed in 7/12 hour

Therefore, all the lawns were mowed in 7/12 × 7 hours = 49/12 hours

This week, Claire mowed 7 lawns

Each lawn was mowed in 5/12 hour

Therefore, all the lawns were mowed in 5/12 × 7 hours = 35/12 hours

To calculate the extra time spent in mowing last week's lawn than this week's, we find the difference between the time spent in mowing all the lawns for the two weeks.

49/12 - 35/12 = 14/12 hours

Therefore, it took Claire 14/12 or 1.17hours longer to mow last week's lawn than this week's.
