125,150,and100 eith graders,whats the ratio
?
ratio to what?
125 : 150 : 100
5 : 6 : 4
Ok, the problem says:
a Middle school has 125 6th graders, 150 7th graders, and 100 8th graders. Which statement is NOT true?
a. the ratio of 6th graders to 7th graders is 5 to 6.
b. the ratio of 8th graders to 7th graders is 3:2.
c. the ratio of 6th graders to students in all three grades is 1:3.
d. the ratio of 8th graders to students in all 3 grades is 4 to 15.
6th - 125
7th - 150
8th- 100
a) ratio 6th:7th
125:150 = 5:6
b) 8th:7th
100:150 = 4:6 = 2:3
c) 6th: total = 125:375 = 5:15 = 1:3
d) 8th:total = 100:375 = 4:15
check your b. ratio 2:3, not 3:2
wait so wich is it a,b,c,d
To find the ratio of the number of fifth graders, eighth graders, and tenth graders, you will divide the number of each grade by the same number. In this case, the number is not specified, so we can use the least common multiple of the three numbers: 100.
To find the ratio:
1. Divide the number of fifth graders by the common number (100):
125 ÷ 100 = 1.25
2. Divide the number of eighth graders by the common number (100):
150 ÷ 100 = 1.5
3. Divide the number of tenth graders by the common number (100):
100 ÷ 100 = 1
Therefore, the ratio of fifth graders, eighth graders, and tenth graders is 1.25:1.5:1.
