38. Calculate [tex]\(\frac{12}{25}\)[/tex] of 5.00.

39. Calculate [tex]\(\frac{3}{5}\)[/tex] of two liters.

Answer :

Sure, let's break down the problem step-by-step to find the answers.

### Question 38: Twelve twenty-fifths of 5.00

1. Understand the fraction: Twelve twenty-fifths can be written as [tex]\( \frac{12}{25} \)[/tex].
2. Determine the value to be multiplied: Here, the value is 5.00.
3. Calculate:
- Multiply [tex]\( \frac{12}{25} \)[/tex] by 5.00.
- First, divide 12 by 25:
[tex]\[
\frac{12}{25} = 0.48
\][/tex]
- Then multiply 0.48 by 5.00:
[tex]\[
0.48 \times 5.00 = 2.4
\][/tex]

So, twelve twenty-fifths of 5.00 is 2.4.

### Question 39: Three-fifths of two litres

1. Understand the fraction: Three-fifths can be written as [tex]\( \frac{3}{5} \)[/tex].
2. Determine the value to be multiplied: Here, the value is 2 litres.
3. Calculate:
- Multiply [tex]\( \frac{3}{5} \)[/tex] by 2.0.
- First, divide 3 by 5:
[tex]\[
\frac{3}{5} = 0.6
\][/tex]
- Then multiply 0.6 by 2.0:
[tex]\[
0.6 \times 2.0 = 1.2
\][/tex]

So, three-fifths of two litres is 1.2 litres.

### Summary of Results:

- Twelve twenty-fifths of 5.00 is 2.4.
- Three-fifths of two litres is 1.2 litres.
