How many tens are in 212?
Lets break it up.
200 has 20 tens
and 12 has 1 ten.
20 + 1 = 21
Answer: 21 tens.
Answer:
10\frac{7}{12}
Step-by-step explanation:
First thing you want to do is find the common denominator for \frac{1}{3} and \frac{3}{4}. You do this by multiplying to denominators together, so 3*4=12.
Next, multiple the numerators with the opposite denominator. 1*4=4 and 3*3=9.
Now you are left with \frac{4][12] and \frac{9}{12}.
Add those back to your numbers
16\frac{4}{12} - 5\frac{9}{12} = 10\frac{7}{12}
46+19+54= 119, so the answer is 119
1hr=60mins
1min=60seconds
1hour=60*60=3600seconds
ratio and proportaion
distance/time=distance/time
39/7=x/3600
times both sides by (7*3600)
140400=7x
divide both sides by 7
20057 and 1/7=x
answer is 20057 and 1/7 meters per hour
or
20.0571428km per hour
