Automobile Maintenance Mandy purchased two new steel-belted all-weather radial tires for her car. The tread depth on the new tires measures 11/32 of an inch. The dealer told her that when the tires have worn down and their tread depth measures 1/8 of an inch, she should replace the worn tires with new ones. How much will the tread depth decrease over the useful life of the tire?

We just gotta subtract them
11 32 1 8
LCD of 32 and 8 is :32
So, get the denominator to be 32
11 32 1 8 11 32 4 32 11 4 32 7 32
So tread depth decreases by 7/32 inches during the useful life of the tires
