Answer :
1. Each if them would get 20 fruits
[tex]23 + 37 = 60[/tex]
[tex]60 \div 3 = 20[/tex]
2. There should be 5 rows of tables needed to sit all the invited guests
On every row there would be 26 people, so then we need to divide 130 by 26 and we get 5. Then if we check, 26 times 5 equals 130.
Hope that helped:)
