16/91 + ?/91 = 1
?/91 = 1 - 16/91
?/91 = 75/91
?/91=1-16/91=91/91-16/91=91-16/91=75/91
\(\frac{16}{91}+\frac{75}{91}=1\)
K mk nha bạn, k mk đi
\(\frac{16}{91}+\frac{?}{91}=1\)
\(\frac{?}{91}=1-\frac{16}{91}\)
\(\frac{?}{91}=\frac{75}{91}\)
\(\frac{75}{91}\)
\(\frac{16}{91}+\frac{?}{91}=1=\frac{91}{91}\)
\(\frac{?}{91}=\frac{91}{91}-\frac{16}{91}=\frac{75}{91}\)
=>\(\frac{?}{91}=\frac{75}{91}\&?=75\)
K nhaaaaaleon
