Выполни сложение: 4/11+6/11=?=?,7/25+2/25=?=?,1/9+5/9=?=?,8/100+34/100=?=?

Answer 1

1) $frac{4}{11}+frac{6}{11} = frac{10}{11}$ (4/11 + 6/11 = 10/11)
2) $frac{7}{25} + frac{2}{25} = frac{9}{25}$ (7/25 + 2/25 = 9/25)
3) $frac{1}{9} + frac{5}{9} = frac{6}{9} = frac{2}{3}$ (1/9 + 5/9 = 6/9 = 2/3)
4) $frac{8}{100} + frac{34}{100} = frac{42}{100} = frac{21}{50}$ (8/100 + 34/100 = 42/100 = 21/50)
