sasha can mow 3 over 8 of an acre of grass in 45 minutes. how many acres of grass does sasha mow per hour?
+23254 One way of looking at this problem;
If you can mow 3/8ths of an acre in 45 minutes, she can mow 1/3rd of that amount in 15 minutes.
1/3 of 3/8 = 1/3 x 3/8 = 1/8th of an acre in 15 minutes.
Since 15 minutes is 1/4th of an hour, multiply what can be done in 15 minutes by 4: 1/8 x 4 = 4/8 or 1/2 of an acre.
