Mary wants to make curtains for the three windows in her living room.For each pair of curtains,she needs material measuring 6ft by 8ft.Altogether how many square yards of material does she need?

geometry 
Ms. Sue,
First change feet to yards.
3 feet = 1 yard
6 feet = 2 yards
8 feet = 2 2/3 yards
2 * 8/3 = 16/3 = 5 1/3 yards for each window
Each window needs 1 pair of curtains.
5 1/3 * 2 * 3 = ? 
geometry 
yuku,
is it 84

geometry 
yuku,
or is it 30 1/3

geometry 
Ms. Sue,
6 * 5 1/3 = 6 * 16/3 = 96/3 = 32 square yards

geometry 
yuku,
so its 32 square yards
