Answer:
3/20
Step-by-step explanation:
If Lorenzo ate 2/5 of his almonds, then the rest of almonds is:
1 - 2/5 = 5/5 - 2/5 = 3/5
So, 3/5 is the share of almonds all the other friends ate. As each friend are the same share and there are 4 friends, so each friend are: (3/5)/4 = 3/(5*4) = 3/20
So, Lorenzo are 2/5 and each friend are 3/20. The total is:
2/5 + (3/20)*4 = 2/5 + 12/20 = 8/20 + 12/20 = 20/20 = 1. So it verify
