Estimations are used to get the approximated value of an expression.

  • The estimate of 432 ÷ 73 is 5.714
  • The estimate of 1,275 ÷ 588 is 1.667

[tex]\mathbf{(a)\ 432 \div 73}[/tex]

Round up to 1 digit

[tex]\mathbf{432 \div 73 \approx 400 \div 70}[/tex]

Divide

[tex]\mathbf{432 \div 73 \approx 5.714}[/tex]

Hence, the estimate of 432 ÷ 73 is 5.714

[tex]\mathbf{(b)\ 1275 \div 588}[/tex]

Round up to 1 digit

[tex]\mathbf{ 1275 \div 588 \approx 1000 \div 600}[/tex]

Divide

[tex]\mathbf{ 1275 \div 588 \approx 1.667}[/tex]

Hence, the estimate of 1,275 ÷ 588 is 1.667
