Number of persimmons that Bryan used
=
58 x 112
= 70
Number of persimmons that Bryan had left
= 112 - 70
= 42
Number of pears that Bryan used
=
35 x 85
= 51
Number of pears that Bryan had left
= 85 - 51
= 34
Fraction of the fruits left that were pears
= 1 -
19=
89 Number of persimmons left = 1 u = 42
Number of pears left in the end
= 8 u
= 8 x 42
= 336
Number of pears that Bryan bought
= 336 - 34
= 302
