Let's solve the mathematical equations step by step:

Equation: 4 - 2 \frac{1}{2}
First, convert the mixed number to an improper fraction:
2 2 1 ​ = 2 5 ​
Now perform the subtraction:
4 − 2 5 ​ = 1 4 ​ − 2 5 ​
We need a common denominator to subtract. The common denominator is 2:
1 4 ​ = 2 8 ​
Now subtract:
2 8 ​ − 2 5 ​ = 2 3 ​

Equation: 6 - 3 \frac{1}{3}
Convert the mixed number to an improper fraction:
3 3 1 ​ = 3 10 ​
Now perform the subtraction:
6 − 3 10 ​ = 1 6 ​ − 3 10 ​
Convert 6 to a fraction with a common denominator:
1 6 ​ = 3 18 ​
Now subtract:
3 18 ​ − 3 10 ​ = 3 8 ​

Equation: 7 - 2 \frac{1}{4}
Convert the mixed number:
2 4 1 ​ = 4 9 ​
Now perform the subtraction:
7 − 4 9 ​ = 1 7 ​ − 4 9 ​
Convert 7 to a fraction with a common denominator:
1 7 ​ = 4 28 ​
Now subtract:
4 28 ​ − 4 9 ​ = 4 19 ​

Equation: 5 - 4 \frac{1}{2}
Convert the mixed number:
4 2 1 ​ = 2 9 ​
Perform the subtraction:
5 − 2 9 ​ = 1 5 ​ − 2 9 ​
Convert 5 to a fraction:
1 5 ​ = 2 10 ​
Subtract:
2 10 ​ − 2 9 ​ = 2 1 ​

Expression: 8 \times 2 \times 4 \times 5
Simply multiply the numbers in sequence:
8 × 2 = 16
16 × 4 = 64
64 × 5 = 320

Equation: 2 \frac{2}{3} - 2 \frac{1}{4}
Convert the mixed numbers to improper fractions:
2 3 2 ​ = 3 8 ​
2 4 1 ​ = 4 9 ​
To subtract, find a common denominator (12):
3 8 ​ = 12 32 ​
4 9 ​ = 12 27 ​
Now subtract:
12 32 ​ − 12 27 ​ = 12 5 ​


I hope this helps clarify how to perform these calculations! If you have any more questions, feel free to ask.
