Answer :
Answer:
28
Step-by-step explanation:
40% 6th graders of 70 total = 28 6th graders
40% 6th graders + 20% 7th graders = 60%
100% - 60% = 40% 8th graders
40% are 8th graders therefore the answer is 28
Hey! ☺️ So, the answer you’re looking for is:
28 eighth graders
28 sixth graders
14 seventh graders.
If there is a total of 70, it means that 100% is 70. We know the percent of students that are in six grade and the percent that are in seventh grade. So we simply just have to add the 40% and 20% to get the 60% we already know. So then you’d subtract the 60% from the 100% to get the final 40% of students.
