Step-by-step explanation:
1.convert the improper fraction into a mixed number 2 1/2. It means 2.5.
2. convert the fraction into decimal number. In 3/10 it means in 0.3, 3 is the tenth.
3.We calculate the approximate value that is why it become 1.285714286
4. We convert the fraction into decimal number. So 1.8 will become 18/10. Reduce the function with 2. So 18/10 (2)/(2) will be 9.5.
5. We convert it in fraction that is why it become 3222/1000. Then reduce the function with 2 so 3222/1000 (2)/(2)=1611/500.
