Question

calcule o resultado das operações a) 3/8+1/6 b) 9/10-1/4 c) 5/9+2/6 d) 11/15-1/2​

Answer 1

$3/8+1/6 = \\\\=\frac{3}{8}+1/6\\\\=\frac{3}{8}+\frac{1}{6}\\\\=\frac{13}{24}$

$9/10-1/4=\\\\=\frac{9}{10}-1/4\\\\=\frac{9}{10}-\frac{1}{4}\\\\=\frac{13}{20}$

$5/9+2/6=\\\\=\frac{5}{9}+2/6\\\\=\frac{5}{9}+\frac{2}{6}\\\\=\frac{8}{9}$

$11/15-1/2=\\\\=\frac{11}{15}-1/2\\\\=\frac{11}{15}-\frac{1}{2}\\\\=\frac{7}{30}$
