it would depend how much you actually used, but you would take the amount you used and divide it by the total amount of yarn. so if the yarn was 4m long and you used 2m then it would be 2/4 which is 0.5 which is also 50%, so half the yarn was used.

Answer:

not possible

Step-by-step explanation:

Among the first 20 natural numbers, the numbers 10, 11, 13, 14, 18, 19 are not possible to make using four 4s and the four basic arithmetic operations.

Below are listed the numbers that can be made and one possible way to do it.

{1, ((4*4)/4)/4}, {2, (4/(4+4))*4}, {3, ((4*4)-4)/4}, {4, ((4-4)*4)+4},

{5, ((4*4)+4)/4}, {6, ((4+4)/4)+4}, {7, (4-(4/4))+4}, {8, ((4*4)-4)-4},

{9, ((4/4)+4)+4}, {12, (4-(4/4))*4}, {15, (4*4)-(4/4)}, {16, ((4*4)*4)/4},

{17, (4*4)+(4/4)}, {20, ((4/4)+4)*4}
