Question

(5/7 + 2/3) : (1 - 5/14 + 1 3/7)=СОРОЧНООООООО!!!​

Answer 1

$\displaystyle (\frac{5}{7}+\frac{2}{3}):(1-\frac{5}{14}+1\frac{3}7})=\frac{29}{21}:(1-\frac{5}{14}+\frac{10}{7})=\frac{29}{21}:\frac{29}{14}=\frac{29}{21}*\frac{14}{29}=\frac{1}{3}*2=\frac{2}{3}$

Answer 2

Answer 3

To simplify the given expression, let's perform the calculations step by step:

Step 1: Simplify the numerator of the first fraction: 5/7 + 2/3 = (15/21) + (14/21) = 29/21

Step 2: Simplify the denominator of the second fraction: 1 - 5/14 + 1 3/7 = 1 - 5/14 + (7/7)(1 + 3/7) = 1 - 5/14 + (7/7)(7/7 + 3/7) = 1 - 5/14 + (7/7)(10/7) = 1 - 5/14 + 70/49 = (49/49) - (5/14) + 70/49 = 114/49 - 5/14 = (1142)/(492) - (57)/(147) = 228/98 - 35/98 = (228 - 35)/98 = 193/98

Step 3: Divide the numerator (29/21) by the denominator (193/98): (29/21) / (193/98) = (29/21) * (98/193) = (2998) / (21193) = 2842 / 4133

Therefore, the simplified form of the expression is 2842/4133.
