Question

Marta has 8 yellow ribbons what are 2 different ways she can place the ribbons on her door or wall write two different addition equations

Answer 1

One way she can place the ribbons is to place them in groups of 8/2=4, making 4+4=8 ribbons (2 groups because 8/4=2). Next, she can put them in groups of 2 (we can make it out of only 2 if we want since 2 is a factor) to get 8/2=4 groups of 2 and 2+2+2+2=8
