  1. 42 * 3 = 126

    126/10 = 12.6

    It looks like they should buy 13 pizzas.

  2. there is 28 students 2 Teachers and 12 extra guests,
    28+2+12=42 People are there

    They need 3 pizza slices each.
    42*3=126 pizza slices are needed.

    A pizza cane only be cut in 10 slices so
    126/10=12.6

    So u need 13 pizzas
