Step-by-step explanation:
Set it up as a proportion in correspondence with their unit of measurement:
![\frac{16}{21,3} = \frac{25}{?} → \frac{[21,3][25]}{16} → \frac{532,5}{16} = 33,28125 \\ \\ 33,3 ≈ P](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B21%2C3%7D%20%3D%20%5Cfrac%7B25%7D%7B%3F%7D%20%E2%86%92%20%5Cfrac%7B%5B21%2C3%5D%5B25%5D%7D%7B16%7D%20%E2%86%92%20%5Cfrac%7B532%2C5%7D%7B16%7D%20%3D%2033%2C28125%20%5C%5C%20%5C%5C%2033%2C3%20%E2%89%88%20P)

Answer:
1/2
Step-by-step explanation:
=[-1/4 + 1/6] ÷ [1/3 - 1/2]
=[-3/12 + 2/12] ÷ [2/6 - 3/6]
=[-1/12] ÷ [-1/6]
=[-1/12] x [-6/1]
= 1/2
18 + 1/2 x (9 - 4) =
18 + 1/2 x 5
18 + 2.5
20.5
20.5 is your answer.
