Answer:
The approximate value of the scale is 1:67
or the actual value without approximation is 1: 66 2/3 ( 66 while number , two over three)
Step-by-step explanation:
Here, we want to figure out the scale in inches of the drawing to the actual object.
The actual object is 500 ft by 700 ft
while the drawing is 90 inches by 126 inches
Mathematically, we know that 12 inches = 1 foot
So the actual object will be;
500(12) by 700(12)
= 6000 inches by 8400 inches
Now let’s make a division to get the scale;
6000/90 by 8400/126
we get 66.67 as answers on both ends
This is approximately equal to 67
So the scale we have here is 1:67
