Answer:
[tex] 8.7 = \frac{3}{5}*8.7 + P[/tex]
Where P represent the kilograms of pears for this case and if we solve for P we got:
[tex] P = 8.7 - \frac{3}{5} *8.7 = 8.7 (1- \frac{3}{5})= 8.7 *\frac{2}{5} = 3.48 Kg[/tex]
And we can check that the total sum is 8.7:
[tex] 5.22 +3.48 = 8.7[/tex]
So then the final answer would be 3.48 Kg of pears
Step-by-step explanation:
For this case we know that the total amount sold was 8.7 Kg. And we know in addition that 3/5 of this weight is from apples. So then the rest [tex]1- \frac{3}{5} = \frac{2}{5}[/tex] correspong to pears.
We can set up the following equation:
[tex] 8.7 = \frac{3}{5}*8.7 + P[/tex]
Where P represent the kilograms of pears for this case and if we solve for P we got:
[tex] P = 8.7 - \frac{3}{5} *8.7 = 8.7 (1- \frac{3}{5})= 8.7 *\frac{2}{5} = 3.48 Kg[/tex]
And we can check that the total sum is 8.7:
[tex] 5.22 +3.48 = 8.7[/tex]
So then the final answer would be 3.48 Kg of pears
