½ - {- 1/3 + [1/5 x (2/6 – 1/6)]} = – 9/5 [ - 2/5 + (- 3/5 – 1/5) – (7/5 – 13/5)] – 1/5 =
[ 8/7 – ½ - ( - 1/14 + 12/18) – (- 7/3 – 5/6) ] =
– { 2/3 + [1/5 – (2/7 + ¾) – 5/4 ] + 1 } =
½ - { 2/5 + [(1/7 – 1/8) – (1/4 – 1/5)] + ½ }

Como puedo resolver estas fracciones? de antemano gracias

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
