Question

H=1/60+1/70+1/80+1/90+1/100

Answer 1

1/60+1/70=7+6/420=13/420

13/420+1/80=4*13+21/1680=73/1680

73/1680+1/90=3*73+56/5040=275/5040=55/1008

55/1008+1/100=25*55+252/25200=1627/25200

Ответ: 1627/25200=0,064563492≈0,065

Answer 2

Ответ:

0.6456...

Объяснение:

$\frac{1}{10}(\frac{1}{6} +\frac{1}{10}+\frac{1}{7}+\frac{1}{9}+\frac{1}{8})$=H

0.1($\frac{8}{30}+\frac{191}{504}$)=0.1· $\frac{1627}{2520}$

$\frac{1627}{25200}$=H

Answer 3

The expression you've provided is a sum of fractions:

H = 1/60 + 1/70 + 1/80 + 1/90 + 1/100

To add these fractions together, you need to find a common denominator and then combine the numerators. The least common multiple (LCM) of 60, 70, 80, 90, and 100 is 25200.

Let's calculate:

H = (25200/60) + (25200/70) + (25200/80) + (25200/90) + (25200/100) = 420 + 360 + 315 + 280 + 252 = 1627

So, the value of the expression H is 1627.
