What is the correct term for cross multiplication?
Cross multiplication IS the correct term!
Can a proportion be equal if the cross products are not equal?
No. A cross product is just a way of simplifying a proportion. If the cross product aren't equal, it follows logically that the proportion isn't equal.
What is the proportion of 2 over 5 equals 7 over x?
Easy. Cross multiply to get 2x = 35. Then, divide by two to get 35/2.
Who invented cross multiplication?
Maths!
What is the rule of cross multiplication?
Cross multiplication is a method used to solve equations involving two fractions set equal to each other. If you have an equation of the form (\frac{a}{b} = \frac{c}{d}), you can cross-multiply to get (a \cdot d = b \cdot c). This technique simplifies the process of finding unknown values in proportion problems. It's particularly useful because it eliminates the fractions, making calculations easier.
What is 3 and two thirds and equals to j over 3?
j = 11. cross multiplication
What is the correct term for cross multiplication?
Cross multiplication IS the correct term!
Is three fourths more one half?
Yes it is. If you use cross multiplication, 3/4 equals 6, while 1/2 equals 4.
A statement that 2 ratios are equal?
A statement that two ratios are equal is called a proportion in math. An example of a proportion is 1/2 equals 2/4. In this proportion, if you cross multiply, you find that 4 x1 is equal to 2 x 2, which is a true statement or proportion.
Can a proportion be equal if the cross products are not equal?
No. A cross product is just a way of simplifying a proportion. If the cross product aren't equal, it follows logically that the proportion isn't equal.
How do you cross simplify?
Cross-simplification is a technique used to simplify the multiplication of fractions. It is possible when the fractions have common factors that can be divided out. For example the multiplication of the fractions 6/2 * 2/5 = (6*2)/(2*5). The 2's can be simplified out so that the multiplication is simply 6/1 * 1/5 = 6/5.
What is the proportion of 2 over 5 equals 7 over x?
Easy. Cross multiply to get 2x = 35. Then, divide by two to get 35/2.
What does Cross multiplication mean?
Cross multiplication is when you multiply the denominator of a fraction by the numerator of another fraction. Before you cross multiply you want to see if you can simply the fractions.
Are the cross products of a proportion equal?
Yes, here's how you can show it, for the equivalent proportions a/b & (n*a)/(n*b): a na -=-- b nb Cross multiply: a*n*b ? b*n*a. Because multiplication is commutative, the question mark is an equal sign.

What happens to the cross products when the terms of a proportion are cross multiplied?
The cross product is created.
