11 and 31 over 40
3/8 of 40 = 15
16/40 + 15/40 = 31/40

In 1 there are 8 eights. So 40 * 8 = 320. So there 320 eights in 40.
if 4 and eight eights is subtracted by 3 and three eights, then you get 1 and five eights
15 is three eights of 40.
Converting all to eights, it gives three eights minus six eights, so the answer is minus three eights.
It is: 3/5+5/8 = 49/40
