10. A wrapping paper fundraiser sells rolls of gold and red wrapping paper. The ratio of gold rolls sold to red rolls sold is 5:8. If the school sells 78 rolls, then how many were gold?​

Respuesta :

The question requires finding the number of rolls of gold wrapping paper.

The number of gold sold is 30 and the number of red sold is 48

Given:

ratio of gold rolls sold to red rolls sold = 5:8

Gold = 5

Red = 8

Total ratio = 5 + 8

= 13

Total rolls sold = 78

Number of gold = 5 / 13 × 78

= 0.3846153846153 × 78

= 30

Number of red = 8/13 × 78

= 0.6153846153846 × 78

= 48

Therefore, the number of gold sold is 30 and the number of red sold is 48
