1st expression is [tex]\dfrac{2}{3}(122+98),[/tex] because

  • the sum of 122 and 98 is 122+98=220;
  • Two-thirds of the sum of 122 and 98 is [tex]\dfrac{2}{3}(122+98)=\dfrac{440}{3}=146\dfrac{2}{3}.[/tex]

2nd expression is [tex]\dfrac{99}{10}\cdot (84+3),[/tex] because

  • the sum of 84 and 3 is 84+3;
  • 99 divided by 10 is [tex]\dfrac{99}{10};[/tex]
  • 99 divided by 10, then multiplied by the sum of 84 and 3 is [tex]\dfrac{99}{10}\cdot (84+3)=\dfrac{99}{10}\cdot 87=\dfrac{8,613}{10}=861.3[/tex]

3. If compare these two expressions, then

[tex]\dfrac{2}{3}(122+98)<\dfrac{99}{10}\cdot (84+3).[/tex]
