Answer:
hello
Thanh have 3,5 meters of fabric. i can say
3,5/1 for it.
and i can say 35/10
now he used three-fourths of a meter of fabric.
its equal to 3/4
now i have to remove 3/4 from 35/10.
35/10 - 3/4
denominators have to be same thats why im expanding them to 20.
35×2/10×2 = 70/20
3×5/4×5 = 15/20
now i can remove 15/20 from 70/20!
70/20 - 15/20 = 55/20
we cannot see 55/20 in the options.
thats why im dividing them with 5.
55÷5= 11 20÷5=4
the answer is 11/4
11/4 = 2and 3/4
so its option 2
good luck(:

Answer:
# of 20cent stamps = 8
Step-by-step explanation:
Let the number 20cent stamps be = x
Let the number 60 cents stamps be = y
Total number of stamps => 20 = x + y ----------- ( 1 )
Total cost of the stamps = 8.80
That is, 0.20x + 0.60y = 8.80 ------------- ( 2 )
( 2 ) => 20x + 60y = 880
=> x + 3y = 44
=> x = 44 - 3y
Substitute x in ( 1 ) => x + y = 20
44 - 3y + y = 20
- 2y = 20 - 44
- 2y = - 24
2y = 24
y = 12
Substitute y = 12 in ( 1 ) => x + y = 20
x + 12 = 20
x = 8
