First, we need to find out how many blue marbles there are in total.
For the big marbles:
3/4 of 160 big marbles = (3/4) * 160 = 120 blue big marbles
For the small marbles:
2/5 of 120 small marbles = (2/5) * 120 = 48 blue small marbles
Total number of blue marbles = 120 + 48 = 168
Total number of marbles = 160 + 120 = 280
Percentage of blue marbles = (168 / 280) * 100% = 60%
Therefore, 60% of the marbles in the box are blue.
For the big marbles:
3/4 of 160 big marbles = (3/4) * 160 = 120 blue big marbles
For the small marbles:
2/5 of 120 small marbles = (2/5) * 120 = 48 blue small marbles
Total number of blue marbles = 120 + 48 = 168
Total number of marbles = 160 + 120 = 280
Percentage of blue marbles = (168 / 280) * 100% = 60%
Therefore, 60% of the marbles in the box are blue.
