Answer:
350 Stamps left
Step-by-step explanation:
First do 5/8*400= 250
Then take 1/5 of it 1/5*250
You end up with 50 so do 250-50= 200 and add the 150 Canadian stamps to get a total of 350 stamps.
You can use the fact that value of a fraction of a number can be calculated by multiplying that fraction with that number.
Peter is left with 350 stamps.
The value of a fraction of a number can be calculated by multiplying that fraction with that number.
For example, 2/3 of 30 is calculated as: [tex]\dfrac{2}{3} \times 30 = 2 \times 10 = 20[/tex]
Count of total stamps = Count of US stamps + Count of Canadian stamps.
Number of US stamps = 5/8 of total stamps.
Total stamps = 400.
Thus,
[tex]\text{Number of US stamps} = \dfrac{5}{8} \times 400 = 5 \times 50 = 250[/tex]
Thus, we have:
400 = 250 + Count of Canadian stamps.
400 - 250 = Count of Canadian stamps.
Count of Canadian stamps = 150
Since Peter gave 1/5 of US stamps to his friend, thus:
[tex]\text{Count of US stamps Peter gave} = \dfrac{1}{5} \times 250 = 50[/tex]
Thus, out of 400 stamps, Peter gave 50 stamps.
Thus, peter is left with 400 - 50 = 350 stamps.
Thus,
Peter is left with 350 stamps.
