H= (9/30303/80808+7/303030/484848)+4,03
H=\(\left(9\frac{30303}{80808}+7\frac{303030}{484848}\right)+4,03\)
\(H=\left(9+\dfrac{3}{8}+7+\dfrac{5}{8}\right)+4.03=17+4.03=21.03\)
Tính hợp lí giá trị biểu thức sau:
H = (9 30303/80808 + 7 303030/484848) + 4,03
H=(9 30303 phần 80808+7 303030 phần 484848)+4,03

TÍNH HỢP LÍ:
A=(\(9\frac{30303}{80808}\)+7\(\frac{303030}{484848}\)) +4,03
\(A=\left(9\frac{30303}{80808}+7\frac{303030}{484848}\right)+4,03\)
\(A=\left(9,375+7,625\right)+4,03\)
\(A=17+4,03\)
\(A=21,03\)
tính nhanh:
C = \(9\frac{30303}{80808}\) + 4,03 + \(7\frac{303030}{484848}\)
\(C=9\frac{30303}{80808}+4,03+7\frac{303030}{484848}\)
\(=9\frac{3}{8}+4\frac{3}{100}+7\frac{5}{8}\)
\(=\left(9+7\right)+\left(\frac{3}{8}+\frac{5}{8}\right)+4\frac{3}{100}\)
\(=16+1+4\frac{3}{100}\)
\(=21\frac{3}{100}\)
