Question

Bài 4 viết 3 phân số tiếp theo khác nhau có cùng tử số mà mỗi phân số đó a, lớn hơn phân số 1/5   b, bé hơn phân số 1/4   c,lớn hơn phân số 1/5 và bé hơn phân số 1/4 giúp tôi với các bạn ơi huhuhu.....

Answer 1

Các phân số đó là:

a):\(\frac{1}{2};\frac{1}{3};\frac{1}{4}\)

b) :\(\frac{1}{5};\frac{1}{6};\frac{1}{7}\) 

c) : \(\frac{4}{19};\frac{4}{18};\frac{4}{17}\) 

Phần c ta quy đồng tử số của 2 phân số nhé :

\(\frac{1}{5}=\frac{4}{20}\)

\(\frac{1}{4}=\frac{4}{16}\)

Answer 2

1/4;1/5;1/6
