53.49 - (28.49 + 9.73) simply calculate 7 out of 13 divided by 7 + 13 out of 6 multiplied by 1 out of 7, 8 out of 7 minus 15 out of 14, 8 out of 1 minus 15 out of 1

53.49-(28.49+9.73)
=(53.49-28.49)-9.73
=25-(10-0.27)
=25-10+0.27
=15.27
1/ ( 7/13 × 7 + 6/13 × 7 )
=1/ ( (7/13+6/13) × 7 )
=1/7
7/8 - 14/15 + 1/8 - 1/15
=(7/8+1/8) - (14/15 + 1/15)
=1-1
=0
