Fraction Flower I think that trying to find out the fraction is a little hard but fun!! The first thing I did was measuring the area of the small triangle. Then, I found the area of the large square.
After that, I set up the fraction with the smaller area for the numerator, and I used the area of the big square for the denominator. I reduced the fraction and got 50/44,000 to 5/4,400 to 1/880.
I was off by a lot. I was off by 1/372. The real answer is 1/512. Bye!!
