We can solve this by expresing their work in rate as how fast they are doing.
Max mows at speed of 1/45
Jan takes 1/90

When we sum those 2 rates we calculate how much will need for them to mow the lawn or in other words their sum to equal 1

1/45x + 1/90 x= 1
3/90x = 1
1/30x = 1
x = 30

Answer is 30

Raymond has two seven foot long boards, and wants to cut fifteen inch long peices from each; what is the greatest number of peic
anastassius [24]

7ft = 84in   84  ÷  15 =  5.6 pieces he can cut from each board.  Since .6 is not a whole piece measuring 15 inches long, he can only cut 5 pieces from each board.

So, 5 x 2 = 10

He would be able to cut 10 pieces measuring 15 inches long.

Hope this helps :)
