Teacher Ana brought 5 cakes to class.
Teachers Silvia and Monica also brought cakes and tripled the number of cakes.
Each cake was divided into 12 slices.
How many students could eat cake if each student eats one slice?
First, we find how many cakes there are in total.
Let's pay attention to the phrase: "Silvia and Monica tripled the number of cakes"
That is, if Ana brings 5 cakes, then now there are:
Now we find the number of slices.
If each cake is divided into 12 slicesand there are a total of 15 cakes, then:
180 total slices. In other words, enough for 180 students.
180
\( 74+32+6+4+4=\text{?} \)
When something is tripled, you multiply by 3. So if Ana brought 5 cakes, tripling means total cakes, not 5 + 3 = 8 cakes.
Each cake is divided into 12 slices. Since we have 15 cakes total, we need to find the total number of slices: slices.
Read the problem step by step! First, find how many cakes there are in total. Then, calculate how many slices you can make from all those cakes.
Make a list! Write down: Ana's cakes = 5, Total after tripling = 15, Slices per cake = 12. Then multiply the last two numbers.
