Fraction that is less than 5/6 and has a denominator of 8

Evgesh-ka [11]

See 5/6 is obviously more than 1/2 so 4/8 works
also 3/8 or 2/8 or 1/8

if you want all fractions then
5/6=x/8

20=3x
divide 3
6 and 2/3=x
basically x/8 such that x<6 and 2/3

Delaware was the first state to enter the Union and Hawaii was the 50th. If we order the positions of entry for the rest of the

Anna71 [15]

Answer:

State A was the <u>12th</u> state to enter the Union. State B was the <u>11th</u> state to enter the Union.

Step-by-step explanation:

Let's call x to the order-of-entry of State B, therefore the order-of-entry of State A is x+1. Given that he product of their order-of-entry numbers is 132:

x*(x+1) = 132

x² + x - 132 = 0

Using quadratic formula:

$x = \frac{-b \pm \sqrt{b^2 -4(a)(c)}}{2(a)}$
