Ratio of 8th graders to 7th graders = 3 : 2
Let the number of graders be 3x and 2x
Number of 8th graders = 18
So , 3x = 18
x = 18/3 = 6
Number of 7th graders = 2 × 6 = 12
Ratio of 6th graders to 7th graders = 5 : 4
Let the number of graders be 5a and 4a
Number of 7th graders = 12
So , 4a = 12
a = 12/4 = 3
Number of 6th graders = 5×3 = 15 ANS

Answer:
Sierra's team has a greater percent of left-handed batters.
25% of Sierra's team bat left handed and 20% of Aubrey's team bat left handed.
Step-by-step explanation:
Sierra: 7/28 = 1/4
1/4 written as a percentage is 25%
Aubrey: 5/25 = 1/5
1/5 written as a percentage is 20%
25% is greater than 20%, so Sierra's team has a greater percent of left-handed batters.
25% of Sierra's team bat left handed and 20% of Aubrey's team bat left handed.
Hope this helps ;)
