Question

X = [ 33/5 CHIA 6 - 0, 125 x 8 CONG 32 / 15 x 0,03 ] x 11/4

l҉o҉n҉g҉ d҉z҉ · Accepted Answer

$x=\left(\frac{33}{5}:6-0,125\cdot8+\frac{32}{15}\cdot0,03\right)\cdot\frac{11}{4}$

$x=\left(\frac{33}{5}\cdot\frac{1}{6}-\frac{1}{8}\cdot8+\frac{32}{15}\cdot\frac{3}{100}\right)\cdot\frac{11}{4}$

$x=\left(\frac{11}{10}-1+\frac{8}{125}\right)\cdot\frac{11}{4}$

$x=\frac{41}{250}\cdot\frac{11}{4}$

$x=\frac{451}{100}$

Câu trả lời:

$x=\left(\frac{33}{5}:6-0,125\cdot8+\frac{32}{15}\cdot0,03\right)\cdot\frac{11}{4}$

$x=\left(\frac{33}{5}\cdot\frac{1}{6}-\frac{1}{8}\cdot8+\frac{32}{15}\cdot\frac{3}{100}\right)\cdot\frac{11}{4}$

$x=\left(\frac{11}{10}-1+\frac{8}{125}\right)\cdot\frac{11}{4}$

$x=\frac{41}{250}\cdot\frac{11}{4}$

$x=\frac{451}{100}$

Phan Nghĩa · Answer

$x=\left(\frac{33}{5}:6-0,125.8+\frac{32}{15}.0,03\right).\frac{11}{4}$

$< =>x=\left(\frac{33}{30}-1+\frac{32}{15}.\frac{3}{100}\right).\frac{11}{4}$

$< =>x=\left(\frac{3}{30}+\frac{32}{500}\right).\frac{11}{4}$
