If you rename 1/4 to 8ths you get 2/8's

So numbers 1/8 unit from 2/8 must be between 1/8 and 2/8

Rename both these fractions but so they have common denominators. I would use 32nds

1/8 = 4/32

1/4= 8/32

So you are looking for fractions between 4/32 and 8/32 like 5/32, 6/32 (or 3/16), and 7/32

Do same for second part of question

1/4 + 1/8 = 3/8

So fractions must be between 1/4 and 3/8

1/4 = 8/32

3/8 = 12/32

So 9/32, 10/32(5/16), and 11/32 are within 1/8 units of 1/4 and greater than 1/4

For your area model, divide a rectangle into 3 columns and shade 2 columns

Then divide the whole rectangle into 5 equal rows and shade 3 complete rows(preferably a different shading than the columns)

The intersection of the two shadings is your product = 6/15 or 2/5

Hope that makes sense since I can't draw it for you
