Answer:
Cross multiplication is the method used to determine whether or not a proportion is true.
Explanation:
If you know one ratio in a proportion, you can use that information to find values in the other equivalent ratio.
Cross multiplication is the method used to determine whether or not a proportion is TRUE.
For example, if a bowl of fruit contains 10 oranges and 8 lemons, then the ratio of oranges to lemons is 10 is to 8 (that is, 10 : 8 ), which is equivalent to the ratio 5:4).
When subtracting fractions, you need to make sure the denominators are the same. In 2/3 - 1/2, the denominators are different. To make them the same, find the least common denominator. In this case, the common denominator is 6
2/3 becomes 4/6
1/2 becomes 3/6
Now subtract the fractions with the common denominator
4/6 - 3/6 = 1/6
The answer is 1/6
