A sewing club used 48 feet of fabric to make 8 blankets. At this rate how many blankets can be made from 6 yards of fabric?

Answers

Answer:

With 6 yards can made 3 blankets

Step-by-step explanation:

First it is necessary to convert 6 yards into feets. This is calculate using a rule of three in which 1 yard is equivalent to 3 feets, so how many feets are 6 yards. This is:

1 yard ------------------ 3 feet

6 yards ---------------- X

Where X is the number of feets that are equal to 6 yards. Then X is equal to:

X=(6 yards* 3 feets)/(1 yard) = 18 feets

Then, using a rule of three, if the sewing club made 8 blankets with 48 feet, then how many blankets could be made with 18 feets. This is:

8 Blankets -------------- 48 feet

       Y        --------------  18 feets

Where Y is the number of blankets that could be made with 18 feets. Solving for Y, we get:

Y=(8 Blankets*18 feets)/(48 feets) = 3 Blankets

So, with 6 yards or 18 feets of fabric the sewing club can made 3 blankets.

48f=8b
÷8    ÷8 (divided by 8)
6f=b
it takes 6 feet of fabric to make 1 blanket 
6f=1b                                                             3f=y
36f=6b
12y=6b

it takes 12 yards to make 6 blankets

There's a 8ft. long board and the carpenter cut off 3 1/2 and 2 1/3.

So first we need to add 3 1/2 and 2 1/3 because the carpenter cut them off the 8ft. long board.

3+2=5 because it's a whole number. 1/2+1/3= 2/6+3/6= 5/6
5 5/6

Now we subtract
8-5 5/6=
7 6/6- 5 5/6= 2 1/6ft.
2 1/6ft. is what remains of the 8ft. board.

Sam paid $8.28 for 18 stamps.at this rate,how much will he pay to buy 12 stamps

Answers

HE WOULD PAY $5.52 FOR 12 STAMPS BECAUSE 8.28/18=0.46 THE YOU USE 0.46 X 12 = AND GET $5.52
lets find the cost per stamp by dividing the cost by # of stamps
$8.28/18 
=$0.46
so if that is the cost per stamp, multiply that by 12 to find the new total cost 
0.46x12
=5.52
