The numbers on two consecutively numbered gym lockers have a sum of 141141. what are the locker numbers?

Let locker A = L
Locker B = L+1

L+L+1=141141
2L +1 =141141
2L=141140
L=141140/2 = 70570

Locker A is 70570
Locker B is 70571

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
