Explanation:
let's bring both fractions to the same denominator to be able to truly compare them in detail.
32 is already a multiple of 4, so we only need to transform 1/4.
1/4 = 1/4 × 8/8 = 8/32
so, the new tire has a tread depth of 8/32 in compared to the typical 5/32 in.
the tread of the new tire is therefore 3/32 in deeper (8/32 - 5/32 = 3/32).
