Howw many gifts are not for you or your cousin?you came to the 128 gifts 1/4 of them have your name on the tag and 1/8 of them are for your cousins how many gifts are not for your cousins

Answer 1

Total gifts: 128

1/4 have your name. Multiply the total number of gifts by 1/4 to get the number of gifts that are for you:

Multiplication of a whole number and a fraction:

`a\cdot(b)/(c)=(a\cdot b)/(c)`

gifts that are for you:

`128\cdot(1)/(4)=(128\cdot1)/(4)=(128)/(4)=32`

1/8 of them are for your cousins. Multiply the total number of gifts by 1/8 to get the number of gifts that are for your cousins:

`128\cdot(1)/(8)=(128\cdot1)/(8)=(128)/(8)=16`

Then, subtract the number of gifts that are for you and the number of gifts that are for your cousins to get the answer of "How many gifts are not for you or your cousin?​":

`128-32-16=80` There are 80 gifts that are not for you or your cousins.

To get the number of gifts that are not for your cousins substract 16 from the total of gifts:

`128-16=112`There are 112 gifts that are not for your cousins
