it's actually easy : just do 50÷4 but then u will get something like 12.5 so if you are confused , you can divide by the closest number to 50 and the number which is a multiple of 4
so,
48÷4 = 12 and with the remaining 2 $ she can buy a half flip flop more if she wants because 4/2
Therefore , the total number of flip flops she can buy = 12½ flip flops
