When finding the area of a figure, you need to multiply. The area has sides of 4 4/9 and 2 1/5. We can multiply these fractions to find the area.
[] Step 1: Convert the mixed fraction to an improper fraction (An improper fraction is when the numerator is bigger than the denominator). []
4 4/9 = 40/9
2 1/5 = 11/5
[] Step 2: Multiply across []
40 * 11 = 440
9 * 5 = 45
= 440 / 45
[] Step 3: Turn the improper fraction into a mixed number (In other words, simplify). []
440 / 45 = 9 7/9

No, it isn't. With 180/20, you can take down the zeros, since both can be divided by 10. So, you get 18/2, but you can still reduce it, for both can be divided by 2. So you end up with 9/1 or 9 in simplest form.
I hope this helps!
