Show answer and explanation

Answer: C. 1/3

Find the number of blue marbles:
1/2 of 340 = 170 blue marbles.
Find the total number of marbles:
340 (red) + 170 (blue) = 510 total marbles.
Find the fraction of blue marbles:
Blue marbles / Total marbles = 170 / 510.
Simplify the fraction:
Divide both numbers by 170:
170 ÷ 170 = 1
510 ÷ 170 = 3
Result = 1/3.
