Gọi 2 số đó là a,b
Ta có
\(\frac{a}{b}=\frac{7}{12}\)
Ta có:
\(\frac{a+10}{b}=\frac{3}{4}=>\frac{a}{b}+\frac{10}{b}=\frac{3}{4}=>\frac{7}{12}+\frac{10}{b}=\frac{3}{4}=>\frac{10}{b}=\frac{3}{4}-\frac{7}{12}=\frac{1}{6}\)
\(=>\frac{10}{b}=\frac{1}{6}=\frac{10}{60}=>b=60=>a=60.\frac{7}{12}=35=>a+b=60+35=95\)
