Leah had 50 stickers . she gave 1/2 two her sister and 2/5 to her brother how many does she have left​

Leah has 15 stickers left.

Step-by-step explanation:

The total number of stickers that Leah had was 50. Leah gave 1/2 of the stickers to her sister. This means that the number of stickers that Leah gave to her sister was: 1/2 × 50 = 25 stickers .

Of the amount left, she gave 2/5 to her brother. This means that the number of stickers that Leah her brother was : 2/5 × 25 = 10 stickers .

Therefore, the number of stickers that Leah have left for herself is :

50 - (25 + 15)

= 50 - 35

= 15 stickers

I hope this helps you!

Have a great day! :)
