so ration magazines sold between Nicole to Lauren" 6:5

6 + 5 = 11

total 165 so 165/11 = 15

15 * 6 = 90
15 * 5 = 75

answer: Nicole sold 90

a. 7:15 and 28:50
No, an equivalent ratio would be 7:15 and 28:60

6. new ratio of Honors to regular is 7:4. 
If 77 in Honors then i would be 44 in regular 

7* 11 = 77
4*11 = 44

150 binders total
48 are red
150 - 48 = 102 are not red

ratio of red to not red
48:102 = 8:17

ratio not red to total
102:150 = 17:25
