Answer: Few phrases make me cringe the way I do when I hear, “Ours is not to reason why; just invert and multiply.” A student’s job in math class is to reason, and a teacher’s job is to help the students see that math makes sense. Understanding division of fractions is complicated, bringing together many ideas that build up to a method that makes sense, especially in the tricky case of a fraction divided by a fraction. Liping Ma writes about research asking teachers to explain what it means to divide by a fraction. Most U.S. teachers were startled to find how difficult this was for them. What if we start with the simpler case of a whole number divided by a fraction?
Answer:
Step-by-step explanation:
The Pythagorean theorem can be used to find the lengths of the segments at the top of the square. The left one is found from ...
FA² = FE² +EA²
13² -12² = EA² = 169 -144 = 25
EA = √25 = 5
The right one is found from ...
FB² = FE² +EB²
15² -12² = EB² = 225 -144 = 81
EB = √81 = 9
Then the length of the side of the square is ...
AB = AE +EB = 5 +9
AB = 14
__
The length of the diagonal can also be found using the Pythagorean theorem.
AC² = AB² +BC² = 14² +14²
AC = √(196 +196) = 14√2 ≈ 19.7990
Rounded to the nearest integer, AC ≈ 20.
