320
40 of 320 would be ---> 40/320 Then we would have ?/100 = 40/320 ----------> ? = (40/320)*100 = 12.5%
640
Since 40 is a factor of 320, it is automatically the GCF.
First we ask ourselves what is 320 ÷ 8? It's 40. Now since we're trying to find 3 of those 8th's we simply multiply 40 x 3 to get 120. Therefore 3/8th's of 320 is 120.
The GCF is 40.
8
The GCF is 40.
It is: 320/800 times 100 = 40%
320 / 8 = 40
320 square feet (8 x 40 = 320)
Multiply the two dimensions to get the area. The calculation will give you 320 square feet.
