1 km = 1000 m
1 hr = 3600 sec. To convert km/hr into m/sec,

Answer:
$150
Step-by-step explanation:
→ Find 3/5 of 1500
( 1500 ÷ 5 ) × 3 = 900
→ Find 6/20 of 1500
( 1500 ÷ 20 ) × 6 = 450
→ Find the sum of the 2 numbers
900 + 450 = 1350
→ Minus it from the original 1500
1500 - 1350 = $150
If the ratios form a proportion, the ratios will be equal. first we'll simplify the ratios:
14/21
divide top and bottom by 7
2/3
26/39
divide top and bottom by 13
2/3
ss you can see now, the ratios are indeed equal, so they do form a proportion
