\(1\frac{13}{15}.\left(0,5\right)^2.3+\left(\frac{8}{15}-1\frac{19}{60}\right):1\frac{23}{24}\)
\(=1\frac{13}{15}.0,25.3+\left(-\frac{47}{60}\right):1\frac{23}{24}\)
\(=1\frac{13}{14}.0,75+\left(-\frac{2}{5}\right)\)
\(=1,4-0,4\)
\(=1\)

Ai lm đc 3 tick nha!!!
giúp P.A zới
Bài 1. Tính:
A= \(1\frac{13}{15}.\left(0,5\right)^2.3+\left(\frac{8}{15}-1\frac{19}{60}\right):1\frac{23}{24}\)
B= \(\left(\frac{11^2}{200}+0,415\right):0,01\)/ \(\frac{1}{12}-37,25+3\frac{1}{6}\)
Giúp mk với
Tính nhanh :1\(\frac{13}{15}.\left(0,5\right)^2\).3+\(\left(\frac{8}{15}-1\frac{19}{60}\right)\div\)1\(\frac{23}{24}\)
\(1\frac{13}{15}\times3\times\left(0,5\right)^2\times3+\left(\frac{8}{15}-1\frac{19}{60}\div1\frac{23}{24}\right)\)
\(\left(-3,2\right)\times\frac{-15}{64}+\left(0,8-2\frac{4}{15}\right)\div1\frac{23}{24}\)
Bài 2 rút gọn\(\frac{2\times\left(-13\right)\times9\times10}{\left(-3\right)\times4\times\left(-5\right)\times26}\)
