A rectangle has been divided into two strips, A and B.
The strips have the same width.
2/5 of strip A is shaded.
5/8 of strip B is shaded.
The length of the rectangle is 40cm.
What fraction of the rectangle is not shaded?
Thank you.
Joseph.

41/40 of the rectangle is shaded so none
3/4 is not shaded
8/5
2/5 x 8 = 16/40
5/8 x 5 = 25/40
16/40 + 25/40 = 41/80 (shaded)
80/80 - 41/80 = 39/80 (not shaded)
5/8 x 5 = 25/40
16/40 + 25/40 = 41/80 (shaded)
80/80 - 41/80 = 39/80 (not shaded)
