Answer: By cross multiplication.
Step-by-step explanation: Given product is 3 × 292.
We know that after simple multiplication, we get 3 × 292 = 876.
Now, to check division with multiplication, either we need to divide 876 by 3 to get the answer 292,
or
we need to divide 876 by 292 to get the answer 3.
We will do that as follows -

Thus, doing cross-multiplication, we arrive at our conclusion.
Given:
The recipe calls for
cup of strawberries for each gallon of lemonade.
Tia has 6 cups of strawberries.
To find:
The number of gallons of lemonade she can make.
Solution:
We have,
cup of strawberries for = 1 gallon of lemonade
cup of strawberries for =
gallons of lemonade
=
gallons of lemonade
=
gallons of lemonade
cup of strawberries for =
gallons of lemonade
=
gallons of lemonade
=
gallons of lemonade
Therefore, 9 gallons of lemonade she can make by using 6 cups of strawberries.
The expression is Undefined for x=0, assuming you intend 1/(-8x).
x=0 is "nonpermissible"
