Okay, so to find this out, we need to place aside 4 inches for Andrea, but we will not add them to her total yet:
Andrea: 0 in
Pierre: 0 in
Total: (152 - 4 =) 148 in
[set aside: 4 in]
Now that the 4inches are set aside, we just need to divide the Total Height in half, because there are 2 people who are sharing this amount:
148 ÷ 2 = 74
Now that we have the answer for this, we now have Pierre's height:
Andrea: 0
Pierre: 74
Total: 74
[set aside: 4 + 74]
And we then take the Set Aside amount, and make it Andrea's height:
Andrea: 78
Pierre: 74
Total: 152
[set aside: 0]
We now have our answer!
I hope this helped!
