Answer 2

I can help you with some math problems. Here are the detailed solutions:

-9*(-8) = 72

To multiply two negative numbers, we change the sign to positive and multiply them normally.

5/9 - 5/12 = 5/36

To subtract two fractions, we need to find a common denominator. The least common multiple of 9 and 12 is 36. Then we multiply both the numerator and denominator of each fraction by the same factor to get the equivalent fractions with the common denominator. Then we subtract the numerators and keep the denominator.

5/9 * 4/4 = 20/36

5/12 * 3/3 = 15/36

20/36 - 15/36 = 5/36

9/20 + 3/8 = 21/40

To add two fractions, we also need to find a common denominator. The least common multiple of 20 and 8 is 40. Then we multiply both the numerator and denominator of each fraction by the same factor to get the equivalent fractions with the common denominator. Then we add the numerators and keep the denominator.

9/20 * 2/2 = 18/40

3/8 * 5/5 = 15/40

18/40 + 15/40 = 21/40

6/25 * 20/9 = 24/225

To multiply two fractions, we just multiply the numerators and the denominators.

6 * 20 = 120

25 * 9 = 225

120/225 = 24/225

0.48 * 9/8 = 0.54

To multiply a decimal by a fraction, we can convert the decimal to a fraction and then multiply the fractions. Alternatively, we can multiply the decimal by the numerator and then divide by the denominator.

0.48 = 48/100

48/100 * 9/8 = 432/800

432/800 = 0.54

Or

0.48 * 9 = 4.32

4.32 / 8 = 0.54

I hope this helps. If you have any other math questions, feel free to ask me.
