Using fractions, it is found that 
of a wheel still needs to be painted.
- On the first wheel, 4 of the 9 equal parts have been painted, that is,
of the wheel has been painted, hence 
has not been painted.
- On the second wheel, 6 of the 10 equal parts have been painted, that is,
of the wheel has been painted, hence 
has not been painted.
The total fraction that still has to be painted is:
of a wheel still needs to be painted.

Answer:
1056
Step-by-step explanation:
Find the area of each square and add them to find the area of the rectangle
The area of a square = side * side
The areas are:
1*1= 1
4*4 = 16
7*7 = 49
8*8 = 64
9*9 = 81
10*10 = 100
14*14 = 196
15*15 = 225
18*18 = 324
The sum of the areas =
324+225+196+100+81+64+49+16+1
= 1056 units ^2
Answer:
Step-by-step explanation:
you can solve for the fractions first, but you have to give them a common denominator
which is in simplest form
then solve for the whole numbers
3-2=1
therefore, the answer is
