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(:
