Why is 1/2 not useful as a benchmark to compare 5/8 and 9/10?

pentagon [3]

1/2 would not be a useful benchmark to compare these 2 fractions because both of them are greater than half. The benchmark fraction 1/2 is most useful when one fraction is less than half and the other more than 1/2. 5/8 is more than 4/8(1/2), and 9/10 is more than 5/10(1/2).

Answer:

b2 = 2A/h -b1

Step-by-step explanation:

The usual formula for the area of a trapezoid is ...

$A=\dfrac{1}{2}(b_1+b_2)h$

We can solve this for b2:

$\dfrac{2A}{h}=b_1+b_2 \qquad\text{multiply by $\dfrac{2}{h}$}\\\\ \dfrac{2A}{h}-b_1=b_2 \qquad\text{subtract $b_1$}\\\\ \boxed{b_2=\dfrac{2A}{h}-b_1}$
