show how you can use repeated subtraction to find how many groups of 7 are in 28.then write the division sentence for problem

Respuesta :

28 - 7 = 21
21 - 7 = 14
14 - 7 = 7
7 - 7 = 0

Therefore 28 - 7 - 7 - 7 - 7 = 0

There are 4 groups of 7, so 28 ÷ 7 = 4
28-7=21
21-7=14
14-7=7
7-7=0

There are 4 sevens
