alan y Pedro comen en la misma escuela pero alan asiste cada 5 días y Pedro cada 7 ¿si coincidieron hoy lunes 10 de enero, cuando volverán a encontrarse​

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.

3. 8,935,200 minutes

4. 227,040 feet

first the equation needs to be simplified. so the equation would now look like:   52-24+11

then you multiply.

and when you multiply, you will get the answer of 39.
