Answer:

Step-by-step explanation:
Given: 10 less than
is 35.
To find: The equation of the given situation.
Solution: We need to write an equation for 10 less than
is 35.
Here, we will break down the sentence to form the equation.
10 less than
means
.
Then, it says 10 less than
is 35 which means it is equal to 35.
So, the sentence 10 less than
is 35 can be written as 10 less than
is equal to 35.
Now, 10 less than
is equal to 35 can be shown as
.
Therefore, the required equation is
.
So you make them the same common denominator
As you see, 2/10 = 8/40
2/4 = x/40, multiply by 10
2/4 = 20/40
Then add because same denominator
Now you would get:
8/40 + 20/40 = 28/40
4+2x = x (x = student in smaller group)
4 + 2x + x = 28 (total # of students)
4+ 3x = 28
3x = 24
x = 8
8 students in the smaller group
4 + 2(8) = 20 students in the larger group
Answer:
18
Step-by-step explanation:
2:3 x 9
18:27
18 + 27 = 45
