Ответ:
Because
3 pillow cases needs 1.5 yards
Then to find 1 pillow case you divide 1.5 by 3
1.5/3= 0.5
One pillow case needs 0.5 yards.
If you have 16.5 yards of fabric, you divide 16.5 by 0.5 to see how many pillow cases can be made by it
16.5/0.5= 33
Hope that makes sense

2 is 10% of 20
solution:
what is 10% of 20?
y is 10% of 20
equation: y = p% * x
solving our equation for y
y = p% * x
y = 10% * 20
converting percent to decimal:
p = 10%/100 = 0.1
y = 0.1 * 20
y = 2
then
answer:
1
1 is 5% of 20
solution:
what is 5% of 20?
y is 5% of 20
equation: y = p% * x
solving our equation for y
y = p% * x
y = 5% * 20
converting percent to decimal:
p = 5%/100 = 0.05
y = 0.05 * 20
y = 1
then
answer:
3
3 is 15% of 20
solution:
what is 15% of 20?
y is 15% of 20
equation: y = p% * x
solving our equation for y
y = p% * x
y = 15% * 20
converting percent to decimal:
p = 15%/100 = 0.15
y = 0.15 * 20
y = 3
then
answer:
0.4
0.4 is 2% of 20
solution:
what is 2% of 20?
y is 2% of 20
equation: y = p% * x
solving our equation for y
y = p% * x
y = 2% * 20
converting percent to decimal:
p = 2%/100 = 0.02
y = 0.02 * 20
y = 0.4
then
answer:
2.5
2.5 is 5% of 50
solution:
what is 5% of 50?
y is 5% of 50
equation: y = p% * x
solving our equation for y
y = p% * x
y = 5% * 50
converting percent to decimal:
p = 5%/100 = 0.05
y = 0.05 * 50
y = 2.5
then
answer:
7.5
7.5 is 15% of 50
solution:
what is 15% of 50?
y is 15% of 50
equation: y = p% * x
solving our equation for y
y = p% * x
y = 15% * 50
converting percent to decimal:
p = 15%/100 = 0.15
y = 0.15 * 50
y = 7.5
then
answer:
1
1 is 2% of 50
solution:
what is 2% of 50?
y is 2% of 50
equation: y = p% * x
solving our equation for y
y = p% * x
y = 2% * 50
converting percent to decimal:
p = 2%/100 = 0.02
y = 0.02 * 50
y = 1
then
answer:
8.5
8.5 is 17% of 50
solution:
what is 17% of 50?
y is 17% of 50
equation: y = p% * x
solving our equation for y
y = p% * x
y = 17% * 50
converting percent to decimal:
p = 17%/100 = 0.17
y = 0.17 * 50
y = 8.5
then the last
answer:
19.5
19.5 is 39% of 50
solution:
what is 39% of 50?
y is 39% of 50
equation: y = p% * x
solving our equation for y
y = p% * x
y = 39% * 50
converting percent to decimal:
p = 39%/100 = 0.39
y = 0.39 * 50
y = 19.5
