Answer:
1/10
Step-by-step explanation:
Since 10 people went somewhere over the summer that is 1/2 of the class.
But going over the whole class 2/20 people went to the beach. Simplified that is 1/10
Train A:
Distance (s) = 420 miles
Time (t) = 3 hours
Speed (v) = distance ÷ time = 420 ÷ 3 = 140 miles/hour
Train B:
Distance (s) = 420 miles
Time (t) = 2.25 hours
Speed (v) = distance ÷ time = 420 ÷ 2.25 = 186.7 miles/hour
Answer:
1:25 (dm:km)
Step-by-step explanation:
For the ratio, you compare two units.
Naturally, we could say that 2 dm corresponds to 50 km
Written in fraction form:
2dm/50km
Simply the fraction normally:
1dm/25km
Just replace the "/" with ":"
1:25 (dm:km)
It would be located on the same spot as 1/5 and to the left of 3/10
