I don't understand this problem can someone please help me? Make an illustration depicting the number line to find the sum of the following:

1 2/3 + 1 5/6

Draw a line and divide into about 22 equal parts. Since you want to divide each whole number into 6 parts, each 6th place is a whole number.

Your line should look something like this.

_._._._._._._._._._._._._._._._._._._._.
