Answer:
16. r = 20
t = 48
17. a = 104
b = 175
19. [tex]\frac{144}{20} =\frac{252}{35}[/tex]
7.2 = 7.2
20. [tex]\frac{27}{18}= \frac{21}{14}[/tex]
1.5 = 1.5
21. [tex]\frac{48}{16} =\frac{36}{12}[/tex]
3 = 3
22. [tex]\frac{8}{3} :\frac{584}{y}[/tex]
219 grams of peanuts
23. [tex]\frac{y}{2}: \frac{200}{80}[/tex]
50 milligrams of medication
Step-by-step explanation:
16. [tex]\frac{r}{32} =\frac{5}{8} =\frac{30}{t}[/tex]
8 · 4 = 32
5 · 4 = 20
r = 20
5 · 6 = 30
8 · 6 = 48
t = 48
17. [tex]\frac{52}{a} =\frac{10}{20} =\frac{b}{350}[/tex]
Here is a different method.
[tex]\frac{10}{20} =\frac{1}{2}[/tex]
52 · 2 = 104
a = 104
350 ÷ 2 = 175
b = 175
22.
[tex]\frac{8}{3} :\frac{584}{y}[/tex]
8 · y = 3 · 584
8y = 1752
8y ÷ 8 = 1752 ÷ 8
y = 219
23.
[tex]\frac{y}{2}: \frac{200}{80}[/tex]
y · 80 = 200 · 20
80y = 4000
80y ÷ 80 = 4000 ÷ 80
y = 50
