Question

rút gọn các phân số sau:

a, \(\dfrac{2023-2023.6}{2023.15}\)

b, \(\dfrac{2025.25+2025.75}{100.7}\)

c,\(\dfrac{1000000}{2025}\)

Answer 1

a, \(\dfrac{2023-2023.6}{2023.15}=\dfrac{2023.\left(1-6\right)}{2023.15}=-\dfrac{5}{15}=\dfrac{-1}{3}\)

b, \(\dfrac{2025.25+2025.75}{100.7}=\dfrac{2025.\left(25+75\right)}{100.7}==\dfrac{2025.100}{100.7}=\dfrac{2025}{7}\)

c, \(\dfrac{1000000}{2025}=\dfrac{1000000:25}{2025:25}=\dfrac{40000}{81}\)
