Question

a container with 2 5/6 gallons of weed killer can spray 3 5/6 lawns. How many gallons would it take to spray 3 lawns?

Answer 1

2 5/6= 17/6
3 5/6= 23/6
17/6÷23/6
17/6×6/23=
17/23=1 lawn
17/23×3=51/23

Answer 2

Answer:

$2\frac{5}{23}$ gallons

Step-by-step explanation:

A container with $2\frac{5}{6}$ gallons of weed killer can spray = $3\frac{5}{6}$ lawans

∵ in $\frac{23}{6}$ lawn the week killer can spray = $\frac{17}{6}$ gallons

∴ in 1 lawn the weed killer is  used = $\frac{17}{6}$ × $\frac{6}{23}$ gallon

∴ in 3 lawns the weed killer can spray = $\frac{17}{6}$ × $\frac{6}{23}$ × 3 = $\frac{51}{23}$ gallon = $2\frac{5}{23}$ gallons
