Answer 3

Let's break down this expression step by step:

1. 0.6/1 - 0.2:

   • 0.6 divided by 1 is 0.6.
   • Subtracting 0.2 from 0.6 gives you 0.4.

2. 3:2/5:

   • The colon ":" in this context usually represents division. So, it's 3 divided by 2, which is 1.5.
   • Then, divide 1.5 by 5, which equals 0.3.

3. 0.75 - 3/20:

   • Subtracting 3/20 from 0.75:
     • Convert 3/20 to a decimal, which is 0.15 (3 divided by 20).
     • Subtracting 0.15 from 0.75 gives you 0.6.

4. 3/4 + 0.35:

   • Add 3/4 to 0.35:
     • Convert 3/4 to a decimal, which is 0.75 (3 divided by 4).
     • Adding 0.75 and 0.35 gives you 1.1.

5. 2:1/2:

   • Again, the colon ":" represents division. So, it's 2 divided by 1/2:
     • When you divide by a fraction, you can multiply by its reciprocal. The reciprocal of 1/2 is 2, so 2 divided by 1/2 equals 4.

6. 0.8/2 - 14:

   • Divide 0.8 by 2, which is 0.4.
   • Subtracting 14 from 0.4 gives you -13.6.

Putting it all together, the expression evaluates to:

0.4 + 0.3 - 0.6 + 1.1 + 4 - 13.6 = -7.4
