Hey i am new and i need
how do you make 9/4 into a mixed number
you

You see how many times the denominator goes into the numerator. For this it would be how many times does 4 fit into 9? the answer would be 2 remainder 1. so you write the mixed number as 2 1/4

So the 2 is the whole number, the 1 is the new numerator, and the 4 stays as the denominator. 

c) 6

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
