Let's work it out together.
Work through one checkpoint at a time. Your answer area opens after the reasoning.
-
Checkpoint 1
Decompose 629 by place value: 629 = 600 + 20 + 9.
-
Checkpoint 2
Multiply each part by 27: 600 × 27 and 20 × 27 and 9 × 27.
-
Checkpoint 3
Add the partial products to combine the full area.
