Solve exercise 2 on page 169 of Math 2 textbook

Problem:

a) Write the numbers 842, 965, 477, 618, 593, 404 according to the model:

842 = 800 + 40 + 2

b) Write according to the model:

300 + 60 + 9 = 369

800 + 90 + 5 =

200 + 20 + 2 =

700 + 60 + 8 =

600 + 50 =

800 + 8 =

a) 842 = 800 + 40 + 2

965 = 900 + 60 + 5

477 = 400 + 70 + 7

618 = 600 + 10 + 8

593 = 500 + 90 + 3

404 = 400 + 4

b) 300 + 60 + 9 = 369

300 + 90 + 5 = 895

200 + 20 + 2 = 222

700 + 60 + 8 = 768

600 + 50 = 650

800 + 8 = 808
