Answer:
61 lawns
Explanation:
"Lawns mowed per hour" is the key to this, and they helped us by asking for that.
Since we want the unit "hours" in the top of the fraction, and "lawns" in the bottom, let's use what we're given and set it up this way:
Taking 14 hours to mow 8 lawns is the same as:
14 hours per 8 lawns, so:
14 h/8 lawns
Which equals 14/8,or 7/4, or 1 & 3/4, or 1.75 lawns per hour.
To find how many lawns could be mowed in 35 hours, simply multiply:
1.75 lawns/hr x 35 hours = 1.75(35) lawns = 61.25 lawns
See how "hours" cancelled out to leave just "lawns"?
And since 0.25 of a lawn isn't a full lawn, you'd round that down to:
61 lawns in 35 hours
