Answer 1

26,000

Explanation:

A national survey of 50,000 sixth graders asked if they know what they would like to do when they get older. Suppose you ask 350 sixth graders if they know what career they want to pursue and 182 student say they do not know. The number of the 50,000 sixth graders that would say they do not know is 26,000.

182 out of 350 students did NOT know.

182 ÷ 350 = 0.52 or 52%

52% = Students who didn't know

50,000 sixth graders in all

50,000 ⋅ 0.52 = 26,000

Therefore, 26,000 students would NOT know.

Answer 2

You asked 350 students, 182 did not know.

182/350 = 0.52 = 52% of the students didn't know.

Multiply the total of the national survey by 52%:

50,000 x 0.52 = 26,000

The answer is 26,000 wouldn't know.
