Katie had 30 stickers. Katie gave 2/3 of the stickers to her sister. Of the amount left, she gave 2/5 to her friend. How many stickers does Katie have left for herself?
gave away 2/3, leaving 1/3
1/3 of 30 is 10
2/5 of 10 is 4
so she has 6 left
To find out how many stickers Katie has left for herself, we need to follow these steps:
Step 1: Calculate the number of stickers Katie gave to her sister.
Katie gave away 2/3 of her 30 stickers, so we need to find 2/3 of 30.
2/3 * 30 = (2 * 30) / 3
= 60 / 3
= 20 stickers
Katie gave her sister 20 stickers.
Step 2: Calculate the number of stickers Katie has left after giving some to her sister.
Katie started with 30 stickers and gave away 20 stickers to her sister.
30 - 20 = 10 stickers
Katie has 10 stickers left after giving some to her sister.
Step 3: Calculate the number of stickers Katie gave to her friend.
Katie gave 2/5 of the remaining 10 stickers to her friend.
2/5 * 10 = (2 * 10) / 5
= 20 / 5
= 4 stickers
Katie gave her friend 4 stickers.
Step 4: Calculate the number of stickers Katie has left for herself.
Katie started with 30 stickers, gave away 20 to her sister, and 4 to her friend.
30 - 20 - 4 = 6 stickers
Katie has 6 stickers left for herself.
Therefore, Katie has 6 stickers left for herself.
To find out how many stickers Katie has left for herself, we need to follow these steps:
Step 1: Calculate how many stickers Katie gave to her sister.
Katie gave away 2/3 of her stickers. To find out how many stickers she gave to her sister, we multiply the total number of stickers by 2/3.
2/3 * 30 stickers = 20 stickers
Step 2: Calculate how many stickers Katie has left.
To find the remaining stickers after giving 2/3 to her sister, we subtract the number of stickers given away from the total number of stickers originally had.
30 stickers - 20 stickers = 10 stickers
Step 3: Calculate how many stickers Katie gave to her friend from what is left.
Katie gave 2/5 of the remaining stickers to her friend. To find out how many stickers she gave to her friend, we multiply the number of stickers left by 2/5.
2/5 * 10 stickers = 4 stickers
Step 4: Calculate how many stickers Katie has left for herself.
To find the final number of stickers Katie has left, we subtract the number of stickers given to her friend from the number of stickers left.
10 stickers - 4 stickers = 6 stickers
Therefore, Katie has 6 stickers left for herself.
