Rachel made 28 hats. Rachel made 7 times as many hats as Greg. Let n be the number of hats that Greg made.
(a) Write an equation that relates the number of hats that they made.
Use 7, n, and 28.
(b) Find n.
n=4 because if we multiply 4, 7 times that will give us 28 and in the question they said that Rachel made 7 times as many hats as Greg. So, that's why n=4.
