Jim thinks –3/5 is greater than –0.2. you determine that –0.2 is greater than –3/5. write jim an explanation that justifies why –0.2 is greater than –3/5. in your explanation, indicate how to use a number line to compare the rational numbers.

First I would introduce the concept of comparing two number using the number line and say: placing two numbers on the number line, the number that is to the right of the other, is the larger number (unless they're equal).

I would then write -0.2 as a fraction: -1/5

Then partition the number line segment between -1 and 0 into fifths and place -1/5 on the first fifth boundary, closes to the 0 point. Then place -3/5 on the boundary of the third fifth (three fifths away from the 0 point into the negative direction). Then ask: which of the two is more to the right on the number line? The answer becomes clear: -1/5 > -3/5 because of the number line comparison concept mentioned at the beginning.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
