Question

rút gọn các phân số 

15/25,18/27,36/64

Answer 1

\(\frac{15}{25}=\frac{3}{5}\);\(\frac{18}{27}=\frac{2}{3}\);\(\frac{36}{64}=\frac{4}{7}\)

k cho mk nhé

Answer 2

\(\frac{15}{25}=\frac{15:5}{25:5}=\frac{3}{5}\)

\(\frac{18}{27}=\frac{18:9}{27:9}=\frac{2}{3}\)

\(\frac{36}{64}=\frac{36:4}{64:4}=\frac{9}{16}\)

Answer 3

15/25=3/5

18/27=2/3

36/64=9/16

k cho mình nha

Answer 4

\(\frac{15}{25}=\frac{15:5}{25:5}=\frac{3}{5}\) 

Vậy \(\frac{15}{25}\)rút gọn bằng \(\frac{3}{5}\)

\(\frac{18}{27}=\frac{18:9}{27:9}=\frac{2}{3}\)

Vậy \(\frac{18}{27}\)rút gọn bằng \(\frac{2}{3}\)

\(\frac{36}{64}=\frac{36:4}{64:4}=\frac{9}{16}\)

Vậy\(\frac{36}{64}\)rút gọn bằng\(\frac{9}{16}\)

Answer 5

\(\frac{15}{25}\)= \(\frac{3}{5}\)

\(\frac{18}{27}\)= \(\frac{2}{3}\)

\(\frac{36}{64}\)= \(\frac{9}{16}\)

Answer 6

Rút gọn 15/25 chia cho 5, 18/27 chia cho 9, 36/64 chia cho 4

Answer 7

15/25=3/5 ; 18/27=2/3 ; 36/64=4/7​

Answer 8

\(\frac{15}{25}=\frac{3}{5};\frac{18}{27}=\frac{2}{3};\frac{36}{64}=\frac{9}{16}\)

đúng thì k ko đúng thì đừng k nhé

Answer 9
