Question

3 5/15+(d-1 7/16)=9 1/16 пж помогите решить

Answer 1

$3 frac{5}{15} + (d - 1 frac{7}{16} ) = 9 frac{1}{16} \ d - 1 frac{7}{16} = 9 frac{1}{16} - 3 frac{5}{15} = frac{145}{16} - frac{50}{15} = frac{2175 - 800}{240} = frac{1375}{240} \ d = frac{1375}{240} + 1 frac{7}{16} = frac{1375}{240} + frac{23}{16} = frac{1375 + 345}{240} = frac{1720}{240} = frac{172}{24} = 7 frac{4}{24} = 7 frac{1}{6}$
