since 50% are grade 6 and 0.3 from 5th grade these equal 8/10 so the fraction of participants from grade 7 would be 2/10

Answer:

Here's how to solve the problem

Step-by-step explanation:

50% of participants are in 6th grade.

100% - 50% = 50

0.3, when converted to percentage form is 30%

50% - 30% = 20%

This remaining 20% is how many participants, out of the whole, are in the 7th grade

20% = 0.2 = 2/10 = 20/100
