Write the ratio of the first measurement to the second measurement.
Diameter of care tire:40cm
Diameter of care tire:18mm
I'm not sure hoow to do this. May someone explain how to do this problem.
40 cm : 18 mm
= 40 cm : 1.8 cm
= 40 : 1.8
= 400 : 18
= 200 : 9
To find the ratio of the first measurement to the second measurement, you need to compare the two measurements and express them as a fraction.
In this case, you are given two measurements: the diameter of a car tire, which is 40 cm, and the diameter of another car tire, which is 18 mm.
To compare these measurements, you need to ensure that they are in the same unit. Since one measurement is given in centimeters (cm) and the other in millimeters (mm), you need to convert one of them to match the other.
Since 1 cm is equal to 10 mm, you can convert the 40 cm measurement to mm by multiplying it by 10.
40 cm * 10 mm/cm = 400 mm
Now that both measurements are in millimeters, you can express the ratio:
Ratio = Measure 1 / Measure 2
Ratio = 400 mm / 18 mm
Simplifying the ratio further, you can divide both sides by the greatest common divisor (GCD) of the numerator and the denominator, which is 2:
Ratio = (400 mm / 2) / (18 mm / 2)
Ratio = 200 / 9
So, the ratio of the first measurement to the second measurement is 200/9.
