Answer:
16. r = 20
t = 48
17. a = 104
b = 175

Explanation:
16.
![(r)/(32) =(5)/(8) =(30)/(t)](https://img.qammunity.org/2022/formulas/mathematics/high-school/946p3digqjo9cpes6v5a514qprnoln2ehb.png)
8 · 4 = 32
5 · 4 = 20
r = 20
5 · 6 = 30
8 · 6 = 48
t = 48
17.
![(52)/(a) =(10)/(20) =(b)/(350)](https://img.qammunity.org/2022/formulas/mathematics/high-school/xeqxs8a5i1v1iyhpfod9jlv3s7cpattpnj.png)
Here is a different method.
![(10)/(20) =(1)/(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/e5nd61jui32jisicwi5ua9uu3kt8176lnq.png)
52 · 2 = 104
a = 104
350 ÷ 2 = 175
b = 175
22.
![(8)/(3) :(584)/(y)](https://img.qammunity.org/2022/formulas/mathematics/high-school/iz2i59uxhocg5l8o8ghl67570u9g5jinft.png)
8 · y = 3 · 584
8y = 1752
8y ÷ 8 = 1752 ÷ 8
y = 219
23.
![(y)/(2): (200)/(80)](https://img.qammunity.org/2022/formulas/mathematics/high-school/injh19tt6pxmntya1d499lub34lk9jaynw.png)
y · 80 = 200 · 20
80y = 4000
80y ÷ 80 = 4000 ÷ 80
y = 50
