Sharing with three friends:
1/24 of original pie
Sharing with little brother:
1/12 of original pie
997/1000, or just round it to 1. <em>If I helped click thanks please (:</em>
She needs 0.1 because 4x4 is 16. :)
30 + 45 = 75
100 - 75 = 25
25% = 0.25
Multiply:
0.25 × 480 = 120
Answer = 120 roses
Hope this helped☺☺
