Answer:
I think it 25/36.
Step-by-step explanation:
The total amount of flour is 4/9 + 1/4. The common denominator of 9 and 4 is 36.
So 4/9 + 1/4 = 16/36 + 9/36 = 25/36
-15=a/5

-75=a
so D

Step-by-step explanation:
Answer:
a 13 students
b 9 groups
Step-by-step explanation:
I will assume we want equal amounts of children from each grade
6th grade:
27 = 3*9 = 3*3*3
7th grade
36 = 4*9 = 2*2*3*3
8th grade
54 = 6*9 = 2*3*3*3
The terms that appear in each of 6th, 7th and 8th are 3*3
That is the greatest common factor
3*3 = 9
We can make 9 groups, Factor out the 9 and what is left is the number from each grade that is in each group
6th grade:
27 = 3*9 There will be 3 6th graders in one group
7th grade
36 = 4*9 There will be 4 7th graders in one group
8th grade
54 = 6*9 = There will be 6 8th graders on one group
In one group we have 3+4+6 = 13 people
There will be 9 groups of 13 children
