Kate ate 1/4 of her orange. ben ate 2/4 of his banana. did kate and ben eat 1/4 + 2/4 = 3/4 of their fruit? explain.

There are two fruits
SO, it will be 1/4*2
                 = 1/8 of total fruit eaten by Kate

Total fraction fruit eaten by Ben= 2/4*2
                                                  = 2/8

So, total fraction of fruit eaten by both Kate and Ben
=1/8+2/8
=1+2/8
=3/8 of the total of both fruit eaten

So, its not 3/4 of their fruit eaten. Instead it is 3/8

The surface area would be 576 because you multiply all the numbers then multiply that number by 6
