My Proof is…
The rectangle has been split into quarters already, so to find out the fractions of the smaller quadrilaterals and triangles. Let’s use number 1 as an example, its clearly ½ of the quarter it is in. So we times the two denominators (the numbers on the bottom of a fraction) together, in this case its 2x4=8 and put the 1 on top, therefore its ⅛. The numerator (the number on top of the fraction) stays the same unless you can simplify it. Therefore using this strategy these are the fractions of the smaller parts of the rectangle.
In conclusion these were my answers:
1= â…› , 2= 1/16 , 3= 3/16 , 4= 1/16 , 5= â…› , 6= 1/16 , 7= 3/32 , 8= 1/32 , 9= 1/32 , 10= 1/64
