Answer: 1 3/4
Step-by-step explanation: First, convert 4 1/2 and 2 3/4 to have like denominators.
4 1/2 = 4 2/4 because 1 x 2 = 2 and 2 x 2 = 4 = 2/4
2 3/4 stays the same.
Now, subtract 4 2/4 - 2 3/4 (4 x 4 = 16 + 2 = 18) and (2 x 4 = 8 + 3 = 11)
18/4 - 11/4 = 7/4 or 1 3/4
The answer is less than.....too sure
Well, one story is 4m 2dm and 17 cm.
now, there are 100 centimeters in 1 meter, so in 4 meters there are 400 cm then.
now, there are 10 decimeters in 1 meter, therefore, 10 centimeters in 1 dm, so in 2 dm is then 20 cm.
in 17 centimeters, is just 17 cm :).
so, the 1 story of the building is 400 + 20 + 17 centimeters, or 437 cm.
now, the building has 17 stories, so 17 * 437 or 7429 cm.
which will then be 7400 cm or 74 meters.
and
20 cm or 2 dm.
and
9 cm.
so, 74 meters, 2 decimeters and 9 centimeters.
Answer:
4) 23.3
5.1) 22.2
5.2) 0.045
Step-by-step explanation:
4) minutes per worksheet = minutes/ worksheets
2 hours and 20 minutes = 120 minutes and 20 minutes = 140 minutes.
6 worksheets in total so:
140/6= 23.333.. (23.3 bar)
5) same thing
total km per total liter = total km divided by total liter= km/l
200/9= 22.22.. ( 22.2 bar)
5.2) same thing but opposite
total liter of total km= l/km = 9/200 = 0.045
