  1. \(189\times 16\)
  2. \(80\times 16\)
  3. \(9 \times 16\)

Solutions

Solution: Answers

  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
