Question

помогите решить 3/10+1/100+4/1000, 6+9/10+7/1000, 30+2+3/100+1/1000, 5+7/10+9/100, 20+8+5/100+6/1000, 90+5/10+7/100+3/1000 это все десятичные дроби

Answer 1

$frac{3}{10} + frac{1}{100} + frac{4}{1000} = frac{300}{1000} + frac{10}{1000} + frac{4}{1000} = frac{314}{1000} = 0,314$

$6+ frac{9}{10} + frac{7}{1000} =6+ frac{900}{1000} + frac{7}{1000} =6+ frac{907}{1000} =6,907$

$30+2+ frac{3}{100} + frac{1}{1000} =32+ frac{300}{1000} +1 frac{1}{1000} =32+ frac{31}{1000} =32,031$

$5+ frac{7}{10} + frac{9}{100} =5+ frac{70}{100} + frac{9}{100} =5+ frac{79}{100} =5,79$

$20+8+ frac{5}{100} + frac{6}{1000} =28+ frac{50}{1000} + frac{6}{1000} =28+ frac{56}{1000} =28,056$

$90+ frac{5}{10} + frac{7}{100} + frac{3}{1000} =90+ frac{5000}{1000} + frac{700}{1000} + frac{3}{1000} =90+ frac{5703}{1000}=90,573$
