\(\frac{43}{20}+\frac{17}{6}:\left[\frac{5}{8}+\frac{7}{30}\right]\)
= \(\frac{43}{20}+\frac{17}{6}:\frac{103}{120}\)
= \(\frac{43}{20}+\frac{340}{103}\)
=\(\frac{11229}{2060}\).
\(\frac{43}{20}+\frac{17}{6}:\left[\frac{5}{8}+\frac{7}{30}\right]\)
\(=\frac{43}{20}+\frac{17}{6}:\left[\frac{103}{120}\right]\)
\(=\frac{43}{20}+\frac{340}{103}=\frac{11229}{2060}\)
a,246:6+1502,5=41+1502=1543
b,43/20+17/6:(5/8+7/30)=43/20+17/6:103/120=43/20+340/103=11229/2060
\(=\frac{43}{20}+\frac{17}{65}:\frac{103}{120}\)
\(=\frac{43}{20}+\frac{408}{1339}\)
\(=2,454705004\)
