Question

Help ! ASAP ! I need it down by 1:10 !

Answer 1

16. r = 20

t = 48

17. a = 104

b = 175

19.
`(144)/(20) =(252)/(35)`

7.2 = 7.2

20.
`(27)/(18)= (21)/(14)`

1.5 = 1.5

21.
`(48)/(16) =(36)/(12)`

3 = 3

22.
`(8)/(3) :(584)/(y)`

219 grams of peanuts

23.
`(y)/(2): (200)/(80)`

50 milligrams of medication

Explanation:

16.
`(r)/(32) =(5)/(8) =(30)/(t)`

8 · 4 = 32

5 · 4 = 20

r = 20

5 · 6 = 30

8 · 6 = 48

t = 48

17.
`(52)/(a) =(10)/(20) =(b)/(350)`

Here is a different method.

`(10)/(20) =(1)/(2)`

52 · 2 = 104

a = 104

350 ÷ 2 = 175

b = 175

22.

`(8)/(3) :(584)/(y)`

8 · y = 3 · 584

8y = 1752

8y ÷ 8 = 1752 ÷ 8

y = 219

23.

`(y)/(2): (200)/(80)`

y · 80 = 200 · 20

80y = 4000

80y ÷ 80 = 4000 ÷ 80

y = 50

Answer 2

16. r = 20, t = 48

17. a = 104, b = 175

19. 144/252, 20/35

20. 14/21, 18/27

21. 16/48, 12/36

22. 219 grams

23. 5 milligrams
