Step-by-step explanation:
Lisha is making headbands using ribbon.
each one requires 15.5 inches of ribbon
For 12 headbands Lisha need to buy ribbon = 15.5 × 12
= 186 inches
Therefore, Lisha will need to buy 186 inches ribbon.
160 inches ribbon is not sufficient to make 12 headbands. She will need to buy 186 inches or more.
You add 5+7 so the total ratio is 12. then divide 48/12=4. you then multiply the given ration 5:7 by 4=20:28. 20 + 28 is 48 students which is given. so there are 28 girls and 20 boys which means there are 8 more girls than boys.
