4/7 / x = 5/15
x = 4/7 / 5/15
x = 13
Ai k mk mk k lại
\(\frac{4}{7}:x=\frac{5}{15}\Leftrightarrow x=\frac{4}{7}:\frac{5}{15}=\frac{12}{7}\)
4/7 : x = 5/15
x = 4/7 : 5/15
x = 12/7
\(\frac{4}{7}:x=\frac{5}{15}\)
\(x=\frac{5}{15}\times\frac{4}{7}\)
\(x=\frac{4}{21}\)
\(\frac{4}{7}:x=\frac{5}{15}\)
\(x=\frac{4}{7}:\frac{5}{15}\)
\(x=\frac{12}{7}\)
Đề bài :4/7 : x = 5/15
Giải: x=4/7:5/15
x=12/7
ủng hộ nha Luchia Nanami
4/7:x=5/15
x=4/7:5/15
x=12/7
nếu thấy đúng thi k nha bạn ai k mik rất cảm ơn !
\(\frac{4}{7}:x=\frac{5}{15}\)
\(x=\frac{4}{7}:\frac{5}{15}\)
\(x=\frac{12}{7}\)
\(\frac{4}{7}\) : X = \(\frac{5}{15}\)
X = \(\frac{5}{15}\) x \(\frac{4}{7}\)
X = \(\frac{4}{21}\)
4/7 : x = 5/15
4/7 : x = 1/3
x = 4/7 : 1/3
x= 12/7
