Sagot :
Answer:
- 6 3/8 yards for 3 aprons
- 5/8 yards left over
- not enough
Step-by-step explanation:
Given that an apron pattern needs 1 3/4 yards of fabric for the front and 3/8 yards for the back, you want to know (a) the amount needed for 3 aprons; (b) the amount left over from 7 yards; (c) whether the remainder is enough for another apron.
a) Amount needed
The amount of fabric needed for 1 apron is the sum of the amounts needed for the front and back.
amount for 1 = (1 3/4 yds) + (3/8 yds) = (14/8 +3/8) yds = 17/8 yds
amount for 1 = 2 1/8 yds
The amount needed for 3 aprons is 3 times this amount, or ...
amount for 3 = 3 × (amount for 1) = 3 × (2 1/8 yds) = 6 3/8 yds
The amount of fabric needed for 3 aprons is 6 3/8 yards.
b) Left over
The amount left over from 7 yards is ...
7 yds - 6 3/8 yds = (6 8/8 - 6 3/8) yds = 5/8 yds
The amount left over from 7 yards is 5/8 yards.
c) Another?
The leftover amount (5/8 yds) is considerably less than the 2 1/8 yards needed for another apron. There is not enough for another apron.
