Answer» length of the fabric =45 1/4length of fabric she took tomake 12 curtains. = 38 1/3length of fabric used to make 4 cushions =45 1/4 - 38 1/3so, convert it into improper fractions = 181/4 - 114/3now find the LCM of the denominator of the fractions which is 12 now bring 12 as the denominator by multiply it by a number gives 12 and with the same number multiply the numerator alsolike this,=181×3/4×3 - 114×4/3×4= 543/12 - 456/12now both are like fractions so subtract it= 543-456/12=87/12so, 87/12 metre fabric is used to make 4 cushion,but the question also says that you have to find length of fabric used to make 1 cushion so we have to divide 87/12 from 4so, 87/12 ÷4 = 87/12÷4/1reciprocal = 87/12 × 1/4 =87/48now convert it into mixed fraction= 1 39/48therefore, 1 39/48 metre fabric was used to make 1 cushion
