Answer 2

To calculate the expression | -9/20 | - | 1 3/5 |, you can follow these steps:

1. Simplify the absolute values: |-9/20| = 9/20 |1 3/5| = 1 3/5

2. Subtract the absolute values: (9/20) - (1 3/5)

Now, you need to subtract the mixed number (1 3/5) from the fraction (9/20). To do this, convert the mixed number to an improper fraction:

1 3/5 = (5 * 1 + 3)/5 = 8/5

Now, subtract the fractions:

(9/20) - (8/5)

To subtract fractions, they must have a common denominator. The common denominator in this case is 20, so you need to adjust the fractions:

(9/20) - (8/5) = (9/20) - (8/5) * (4/4) = (9/20) - (32/20)

Now that both fractions have the same denominator, you can subtract them:

(9/20) - (32/20) = (9 - 32)/20 = (-23/20)

So, |-9/20| - |1 3/5| is equal to -23/20.
