It rains 0.7 inch on Wednesday and 0.31 inch on Thursday. Brandon draws this model to find how much more rain falls on Wednesday than on Thursday.
Which equation does the model represent?
1.0 - 0.7 = 0.3
1.0 - 0.31 = 0.69
0.7 - 0.31 = 0.39
0.7 - 0.4 = 0.3
Which equations can you use to find 27.13 - 19.85? Choose all the correct answers.
19.85 + n = 27.13
27.13 + n = 19.85
n = 19.85 + 27.13
19.85 = 27.13 - n
27.13 = n - 19.85
