What is the unit fraction for 12/84

Answers

To simplify 12/84 find the greatest common factor, the greatest factor shared by both numbers. In this case, it is 12 itself. Divide both sides by 12 to get 1/7.

A student solved this problem by working backwards. Riley has some gerbils. He has 4 times as many as Lukas. Lukas has 2 gerbils. Riley gave 5 away and bought 2 more. How many gerbils does Riley have now?

Students's solution: Lukas has 2 gerbils, so Riley had 2 × 4 to begin with. So Riley had 8 gerbils. He gave away 5, so 8 – 5 = 3. He bought 2, so 2 + 3 = 5. So Riley has 5 gerbils.

Here is another problem that can also be solved by working backwards.

If each quadrilateral below is a rectangle find the missing measure in #3

Answers

You can solve this exercise as below (View the figure attached):

1.Divide the figure in four equals parts. Now we have 4 rectangles with the same dimensions.
2.Choose the rectangle that has the angle given in the problem, which we will call "α" (α=59°).
3. We must remember that the sum of the internal angles of a triangle is 180°. We have α=59° and the right angle, so we can find the other one, which we will call "β1":
β1=180°-90°-59° β1=31°
4. As we can see in the figure, "α" is alternate interior with α1 (α=α1=59°) and β1 is alternate interior with m∠11 (β1=m∠11=31°).
5. The others rectangles have the same dimensions of the rectangle we chose, so they have the same angles too.
We can notice in the figure that m∠7+m∠8+m∠9+m∠10= 360°

The answer is:
m∠1=59°
m∠2=31°
m∠3=59°
m∠4=31°
m∠5=31°
m∠6=59°
m∠7=118°
m∠8=62°
m∠9=62°
m∠10=118°
m∠11=31°
