Hi,
A can lay a lawn in 10 hours, B can lay a lawn in 8 hours.
What fraction of the lawn will A lay in one hour? 1%2F10
What fraction of the lawn will B lay in one hour? 1%2F8
What fraction of the lawn would be laid in one hour working together? %281%2F10%29+%2B+%281%2F8%29+=+18%2F80+=+9%2F40
How long would it take to lay the entire lawn?
%289%2F40%29%2F1hr+=+%2840%2F40%29%2Fx
x = 40/9 = 4.44hrs
