Tính giá trị biểu thức. 24 × 7 – 676 : 13 (375 – 24 × 15 ) + 98

a) 24 × 7 – 676 : 13

= 168 – 52

= 116

b) (375 – 24 × 15 ) + 98

= (375 – 360) + 98

= 15 + 98= 113

c) \(\frac{{84}}{{54}}\,\, - \,\,\frac{{10}}{{36}}\,\, \times \,\,\frac{{14}}{5}\)

\( = \frac{{14}}{9} - \frac{{10 \times 14}}{{36 \times 5}}\)

\(\begin{array}{l} = \frac{{14}}{9} - \frac{7}{9}\\ = \frac{7}{9}\end{array}\)

d) \(5\,\, - \,\,\frac{{35}}{{24}}\,\,:\,\,\frac{5}{8}\)

\( = 5 - \frac{{35}}{{24}} \times \frac{8}{5}\)

\( = 5 - \frac{7}{3}\)

\( = \frac{8}{3}\)
