First man mows the lawn in 6 hours so he mows 1/6 of the lawn per hour
Second man mows at 1/4 lawn per hour
Third man mows at 1/3 lawn per hour
The total of the three: 1/6 + 1/4 + 1/3 = 2/12 + 3/12 + 4/12 = 9/12 = 3/4 of a lawn per hour.
1 lawn / 3/4 lawn per hour = 1 and 1/3 hours all together.
Answer: 1 and 1/3 hours

Answer:
0.437
Step-by-step explanation:
Decimals are read the same as whole numbers, starting with the first digit, which is the largest, to the right. So, to find the larger decimal you need to look at the first digit. If this digit is the same then continue to the right until there is a difference in the number. In this case, the first digit is different. Therefore, whichever has the larger first digit must be the greater one. Since 4 > 3, 0.437 must be greater than 0.347.
