Hey there!
The main concept of pre-algebra is solving equations for variables in them.
For example, let's say you have the algebraic equation below.
x+1=3
With algebra, you need to figure what x is equal to. To do so, you will use inverse operations on both sides of the equation to isolate x one side, showing what it is equal to.
We would subtract 1 to both sides to isolate x on one side.
x+1-1=3-1
As you can see, +1-1=0, therefore, this would give us x+0, or just x. Now it is isolated and will show us what it is equal to.
x=3-1
x=2
Therefore, in our equation x+1=3, x would be equal to 2.
I hope this explanation helps! Have a great time here at Brainly!
1/3 because on total has to be 1 or 9/9 but if she use 3 yards of 9/9 then she use 3/9 and if you simplify is 1/3

Only 6 i believe but idrk
Answer:
16/15
Step-by-step explanation:
Ratio: 3/4 : 4/5
Whole number ratio: 15 : 16
You need to divide both sides by 15 so you can turn 15 to 1
Divide both sides of the ratio by 15: 1 : 16/15
So, for 1 pound of flour, you need 16/15 pounds of brown sugar for a cake.
