Okay well thins is how I do it. Divide 100 by 5. That is 20. So then multiply 1/4 by 20. I change it to a decimal so .25×20=5. ANSWER: the scale drawing would be 5 inches.
The 100 yards is represented by 5 inches
What is Unitary method?
It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Steps to Use Unitary Method
First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.
Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.
Given:
5 yards= 1/4 inch
1 yard = 1/ (4*5)
1 yard= 1/20
Now,
100 yards= 1/20 *100
100 yards= 100/20
100 yards= 5 inches.
