Answer:
0.14 inch
Step-by-step explanation:
We are given three coins with width 0.7, 0.84 and 0.74 inches.
Now, as 0.84 > 0.7 and 0.84 > 0.74.
Thus, the coin with the largest width is the coin of width 0.84 inch.
Also, as 0.7 < 0.74 and 0.7 < 0.84.
So, the coin with the smallest width is the coin of width 0.7 inch.
Therefore, the difference in the largest and smallest width of the coins is 0.84 - 0.7 inch i.e. 0.14 inch.
Hence, the difference in width is 0.14 inch.
