• You don't need yo use the number line you can just add the numerator (っ °Д °;)っ
• I don´t under stand. Can you be a little more specific?

• In this video, Sal is solving a word problem by subtracting a mixed number from another fraction. He starts with a table of values that Lily found when she measured the depth of three different puddles.

Sal wants to find out how much deeper the puddle under the swing (the last one listed in the table) than the puddle on the sidewalk (the middle one listed in the table).

At about @, Sal starts converting the mixed number into an improper fraction (a fraction with its numerator larger than its denominator).

At about @, Sal subtracts the depth of the smaller puddle from the depth of the larger puddle to find the difference between the puddles.

At about @, Sal creates a visual representation of 1 1/4 and shows what happens when 2/4 are removed from 1 1/4. He gets the same result in the visual representation that he got when he did the arithmetic.
