Right.
To subtract fractions, follow these steps:
Step 1: Find a common denominator for the fractions. The denominator is the bottom number of each fraction. In this case, the denominators are 9 and 12. The smallest number that these two numbers divide into evenly is 36.
Step 2: Convert the fractions so that they have the same denominator. Since 9 goes into 36 four times, multiply both the numerator and denominator of 8/9 by 4, resulting in 32/36. Similarly, since 12 goes into 36 three times, multiply both the numerator and denominator of 7/12 by 3, resulting in 21/36.
Step 3: Subtract the numerators while keeping the common denominator. 32/36 - 21/36 is equal to 11/36.
Therefore, the answer to the problem 8/9 - 7/12 is 11/36.
For the second question, to multiply fractions, follow these steps:
Step 1: Multiply the numerators (top numbers) together. In this case, multiply 2/9 by 18, resulting in 36.
Step 2: Multiply the denominators (bottom numbers) together. 9 multiplied by 1 is 9.
Step 3: Write the product as a fraction with the multiplied numerators as the new numerator and the multiplied denominators as the new denominator. So, 36/9 can be simplified to 4.
Therefore, the answer to the problem 2/9 * 18 is 4.
