mrs. escorrido, a dressmaker bought 2 1/8 meter of material to make a blouse and 2 3/4 meter of the same material to make a dress in tagaytay city public market, how much material did she buy altogether? how much more material did she use for making a dress than a blouse?

Answer 1

since 3/4 = 6/8,
altogether, 2 1/8 + 2 3/4 = 4 7/8
the difference is, of course, 2 3/4 - 2 1/8 = 5/8

Answer 2

2.125 + 2.75 = ?

2.75 - 2.125 = ?
