11.) our question issss..... 7 x __ = 420 all we have to do here is the opposite. so lets divide 420 by 7 here the math 420/7 = 60 sooooo answer is 60
12.) our question issss.... 50 x __ = 0 well always keep in mind anything we multiply by 0 is going to be zero so for example if we did 4 x 0 is would equal 0 because there arent even any rows to begin with so your answer issss 0! have a good one :)
