::每个人都吃多少巧克力?Chocolate Bar Four friends break a chocolate bar into pieces to share evenly. In this interactive, distribute the chocolate bar evenly by dividing it evenly among the friends. Figure out what fraction of the total chocolate bar each friend gets. Later in this lesson, you will use tape diagrams to divide with fractions.
::四位朋友将巧克力条折成块以平均分享。 在此互动中, 平均分配巧克力条, 并在朋友之间平均分配。 找出每个朋友的巧克力条总分数。 在此课后, 您将使用磁带图将巧克力条和分数分开 。+Do you want to reset the PLIX?
