12,75* 4/25*1,8       12,75* 0,08* 1,8       1,836
---------------- = ---------------= ------- = 12
1 1/2*2,04: 20          1,5* 2,04: 20          0,153

Answer 2

Let's break down the expression step by step:

12.75 * 4 / 25 * 1.8

First, we perform the multiplication:

12.75 * 4 = 51

Next, we perform the division:

51 / 25 = 2.04

Finally, we perform another multiplication:

2.04 * 1.8 = 3.672

So, the result of the expression 12.75 * 4 / 25 * 1.8 is 3.672.

Moving on to the next expression:

1 1/2 * 2.04 / 20

First, we need to convert 1 1/2 to a decimal. We can do this by adding the whole number (1) to the fraction (1/2):

1 + 1/2 = 3/2

Next, we perform the multiplication:

3/2 * 2.04 = 3.06

Finally, we perform the division:

3.06 / 20 = 0.153

So, the result of the expression 1 1/2 * 2.04 / 20 is 0.153.
