Jonah measured a picnic area near the river and made a scale drawing. The picnic area, which is 70 yards wide in real life, is 10 inches wide in the drawing. What scale did Jonah use?
1 inch:___ yards
To determine the scale, we need to find the ratio between the width of the picnic area in real life and the width of the drawing.
1 inch: ___ yards.
Given that the width of the picnic area in real life is 70 yards and the width of the drawing is 10 inches, we can set up the following proportion:
1 inch / width in drawing = 1 yard / width in real life
1 inch / 10 inches = 1 yard / 70 yards
Simplifying this equation gives:
1/10 = 1/70
To find the value of 1 inch in yards, we can cross multiply:
(1)(70) = (10)(1)
70 = 10
Therefore, the scale that Jonah used is:
1 inch: 7 yards.
