Justin, Sam, and Andra have weekend jobs mowing lawns for money. At the end of the day on Saturday, Justin had mowed 2__ 1 4 times as many lawns as Sam had and Andra had mowed __ 1 2 as many lawns as Justin had. Who mowed the most lawns? Who mowed the least number of lawns?

Highest = Justin

Least = Sam

Step-by-step explanation:

Given

Represent Justin with J, Sam with S and Andra with A.

From the question, we understand that

J = 2¼ of S

A = ½ of J

Required

Determine who mowed the most and who mowed the least.

J = 2¼ of S

J = 2¼ * S

J = 2¼S

Also,

A = ½ of J

A = ½ * J

Substitute 2¼S for J

A = ½ * 2¼S

Convert to improper number

A = ½ * 9/4S

A = 9/8S

Convert to mixed number

A = 1⅛S

The above expression implies that Andra mowed 1⅛ lawns as Sam had.

To get a clearer picture of the question.

Assume that:

S = 16

i.e Sam mowed 16 lawns

Substitute 16 for S in A = 1⅛S

A = 1⅛ * 16

A = 9/8 * 16

A = 9 * 2

A = 18

Also, substitute 16 for S in J = 2¼S

J = 2¼ * 16

J = 9/4 * 16

A = 9 * 4

A = 36

By comparison

36 > 18 > 16

Or

J > A > S

This implies that;

Justin mowed highest and Sam mowed the least

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent
