Gabriel measured a house and made a scale drawing. The garage, which is 12 meters long in real life, is 4 millimeters long in the drawing. What scale did Gabriel use for the drawing?1 millimeter : __ meters
Q. Gabriel measured a house and made a scale drawing. The garage, which is 12 meters long in real life, is 4 millimeters long in the drawing. What scale did Gabriel use for the drawing?1 millimeter : __ meters
Given lengths: We have:Length of the garage in real life = 12 metersLength of the garage in drawing = 4 millimetersWe need to find the ratio of the length in the drawing to the length in real life to determine the scale.Ratio = Length of the garage in drawing / Length of the garage in real lifeRatio = 4mm/12m
Convert to same units: To compare the lengths in the same units, we need to convert meters to millimeters because the drawing is measured in millimeters. We know that 1 meter =1000 millimeters.So, 12 meters =12×1000 millimeters =12000 millimeters.
Find ratio: Now we can find the scale by dividing the length of the garage in the drawing by the length of the garage in real life (in millimeters).Scale = 12000mm4mm
Simplify ratio: Simplify the scale by dividing both the numerator and the denominator by 4.Scale = (4/4)mm/(12000/4)mmScale = 1mm/3000mm
Final scale: Since we want the scale in terms of millimeters to meters, we need to convert the denominator back to meters from millimeters.3000 millimeters =10003000 meters =3 metersSo, the scale is 1 mm : 3 m
