The ratio is 10 to 18, therefore 10 * nr of students = 18 * nr of girls.
So the number of girls = nr of students * 10 / 18 which is indeed 150.
Answer:
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 = <u>25 stickers</u>
.
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 = <u>10 stickers
</u>.
Therefore, the number of stickers that Leah have left for herself is
:
50 - (25 + 15)
= 50 - 35
= <u>15 stickers</u>
