Answer:

7 7/8

Step-by-step explanation:

There are several ways to get there.

2.25×3.5 = 7.875 = 7 7/8

(2 1/4)(3 1/2) = (9/4)(7/2) = 63/8 = 7 7/8

(2 1/4)(3.5) = 2(3.5) +(1/4)(3.5) = 7 + (2·3.5)/(2·4) = 7 +7/8 = 7 7/8

A typical graphing calculator will let you enter this problem directly, giving you a result either as a decimal, improper fraction, or a mixed number.
