A group of 45 singers will march behind a group of 30
comedians in a parade. You want to arrange the two groups
in rows with the same number of participants in each row,
but without mixing the group. What is the greatest number of
people you can have in each row?​


Sagot :

Answer:

5

Step-by-step explanation:

45÷5=9

↕️

30÷5=6

45= 1, 3, 5, 9, 15, 45

30=1, 2, 3, 5, 6, 10, 30

because 5 is the gcf of 45 and 30
