Hey There :)
This is because one is half of two. You could also multiply 2 * 0.5= 1, 0.5 represents

and two is the whole number. This is how

of two equals one.

You would use unit rate for this. If Austin makes $209 in 11 hours, then he makes 209/11 = 19 dollars in 1 hour.
Then, we can make a proportion:
$19/1 hour = $152/ x hours
Cross multiply:
152 = 19x
Solve for x to get:
x = 8 hours.
√5 x√5 x√8= √(5x5x8) = √200 = 10 √2
It’s an irrational number
It is 70 because common sense people
