Interpreting a Division Computation


Alignments to Content Standards: 6.NS.B.2

Task

Use the computation shown below to find the products.

Long_division_b1f6143dc37e0eebcef76574e0b30e75

  1. $189\times 16$
  2. $80\times 16$
  3. $9 \times 16$

Solution

  1. $189\times 16 = 3024$. The computation shows that $3024 \div 16$ is $189$ with a remainder of $0$. So it must be that $189\times 16 = 3024+0$.

  2. $80\times 16=1280$. We can see this in the second step of the division algorithm. Sol_1_9c923adc41db2e4a4bd50185b1c80116

  3. $9 \times 16=144$. We can see this in the last step of the division algorithm. Sol_2_f72644aa2f7db41212a806f26a3a683a
