Question 14. Tom wants to divide a pizza into two halves. He also wants to have the same number of tomatoes on each half. It is possible for him to do this with two different cuts.  Along which lines could he cut? Let's start off by taking a closer look at the pizza. You see that we have several different options. Let's start off with the one.  If Tom cuts the pizza at the one line, let's count the number of tomatoes on this side. When we count them up, we get 10 slices of tomatoes.  On the other side, we see that we have eight. We do not have an equal amount of tomatoes when we do this, so options A and B will be thrown out, since the cut at number one  does not give us an even number of tomato slices. Next, let's try cutting the pizza at the number two slice. Here we see we have nine slices of tomatoes,  and on the other side we have nine again. So, the number two cut gives us the correct even amount of slices of tomatoes. This means that option E can be discarded, since it does not  include the number two cut. Now, if Tom cut it at number three, we would have eight slices of tomatoes on this half, and ten on this half. This means we can throw out  option C, since it has number three as an option, and we will be left with D, two, and four.

Video Summary

Tom aims to divide a pizza into two halves with an equal number of tomato slices using two possible cuts. After examining the options, cutting along line number two results in both sides having nine tomato slices each. The analysis finds that cutting at line number three doesn't yield equal tomato distribution, eliminating option C. Therefore, the suitable options for Tom to achieve equal division are D, which includes lines two and four, ensuring both halves of the pizza have the same number of tomatoes.
