21.) 42:y = 30:90 (direct proportion)
Stremes: 42,90 Means: y,30
42×90=y×30
3,780 = 30y
3,780/30 = 30y/30
y = 126
check:
→ 42:126 = 30:90
42×90 = 3,780
126×30 = 3,780
22.) 36:10 = y:60 (inverse proportion)
X↓1Y↓1 = X↓2Y↓2
36×10 = y×60
360 = 60y
360/60 = 60y/60
y = 6
check:
→ 36:10 = 6:60
36×10 = 360
6×60 = 360
23.) 4y:24 = 30:4 (direct proportion)
stremes: 4y,4 means: 24,30
4y×4 = 24×30
16y=720
16y/16 = 720/16
y = 45
check:
→4(45):24 = 30:4
4(45)×4 =720
24×30=720
24.)6:6y = 50:90 (direct proportion)
stremes: 6,90 means: 6y,50
6×90 = 6y×50
540 = 300y
540/300 = 300y/300
y=1.8
check:
→6:6(1.8) = 50:90
6×90 = 540
6(1.8)×50 = 540
25.) 24:10y = 54:130 (inverse proportion)
X↓1Y↓1 = X↓2Y↓2
24×10y = 54×130
240y = 7,020
240y/240 = 7,020/240
y = 29.25
check:
→24:10(29.25) = 54:130
24×10(29.25) = 7,020
54×130 = 7,020
