1 2/5 = 3.36

So 2/5 is 0.4

1.4 = 3.36

Now we have to figure out 2 3/4

3/4 is 0.75


set up a proportion

1.4 = 3.36

2.75 = X

Let's Cross Multiply

1.4X = 9.24

X = 9.24/1.4

X = 6.6

So, it costs 6.6 dollars for 2 3/4 pounds of lunch meat.
 We know that 1 2/5 lbs = 1.4 (decimal). We also know that 2 3/4 = 2.75.

1.4 lbs costs $3.36.

Divide 2.75 by 1.4:

2.75 / 1.4 = 1.964 (rounded)

Multiply $3.36 by 1.964:

3.36 * 1.964 = 6.599

So, 2 3/4 lbs of meat would cost $6.60.
