Answer:
For your area models you would draw two rectangles and divide one into 2 equal sections, and the other one with 8 equal sections. You then shade 1 box out of the first triangle with 2 equal sides. Then you would shade 7 boxes on the rectangle with 8 equal sides. These diagrams would show you that 7/8 and 1/2 are not equivalent.
To find out what fractions are equivalent to 1/2 you would take 1/2 and times the numerator and denominator by the same number.
1/2*2/2= 2/4
2/4=1/2
1/2*9/9= 9/18
9/18=1/2
2/4 and 9/18 both equal 1/2

10.98 = 1/2b (3.6)
10.98=b/2 (3.6)
10.98=b (1.8)
10.98/1.8=b
6.1=b
