(3-1/2) x (2-1/4) = (7/2) x (9/4) = 63/8 = 7-7/8
===============================
Another approach:
3-1/2 = 3.5
2-1/4 = 2.25
(3.5) x (2.25) = 7.875 = 7-7/8

yes 1/4+1/4 = 1/2 0.25+0.25=0.5
1 and 1/4
1/2 x 1/2 = 1/4 The numbers make sense, since you're multiplying 1 x 1 and 2 x 2 but the concept doesn't because you think you're multiplying two larger numbers to get one smaller one. That's the way it is with fractions. Think of it this way. 1/4 + 1/4 = 1/2 That means there are two quantities (1/4 each) that make up 1/2 One half of two fourths is one fourth.
Two to the fourth power times 5 to the fourth power equals 10,000
1/4 x 2 = 2/4 = 1/2
edmondo says no BigMommaRhonda says yes- 1/2 of 1= 1/2, 1/2 of 1/2= 1/4.
1/2 x 2 is the same as 2/2...which equals 1.
2x1/4 +1/2= 2/4 + 1/2= 1/2+1/2 =2/2 =1
2 and 1/4 * 5 and 1/3 = 12
21/4 + 11/2 = 9/4 + 3/2 = 9/4 + 6/4 = 15/4 = 33/4
