Amodel car is built on a scale of 2: 21 of a real car . if the real car has a height of 1.7 meters , what is the height of the model in centimeters ?i will mark you as brainliest

To get from the real value to the model value, you must divide by 21 and times by two (since 21/21 = 1 and 1 x 2= 2 in the ratio) this is the same as multiplying by the fraction 2/21.
So, 1.7 x 2/21 = 17/105 = 0.16m or 16cm

Ithink it is15not sure tho
