Answer 1

$2 \frac{1}{48}-1 \frac{55}{72}= \frac{97}{48}- \frac{127}{72}= \frac{291-254}{144}=\frac{37}{144}$

Answer 2

2 1/48 - 1 55/72 = 2 3/144 - 1 110/144 = 291/144 - 254/144 = 37/144.

Answer 3

To solve the expression 2.1/48 - 1.55/72, we need to find a common denominator for the fractions and then subtract them.

First, let's find a common denominator for 48 and 72. The least common multiple (LCM) of 48 and 72 is 144.

Next, we need to rewrite the fractions with the common denominator of 144:

2.1/48 = (2.1 * 3)/ (48 * 3) = 6.3/144 1.55/72 = (1.55 * 2)/ (72 * 2) = 3.1/144

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

6.3/144 - 3.1/144 = (6.3 - 3.1)/144 = 3.2/144

Therefore, the solution to the expression 2.1/48 - 1.55/72 is 3.2/144.

Please note that the above solution is based on the assumption that the expression is written as a subtraction of two fractions. If there is any ambiguity in the expression or if it is written differently, please let me know and I'll be happy to help further.
