Question

Х:1,15=0,16
0,408:х=1,7

Answer 1

$x \div 1.15 = 0.16$

$x \div \frac{23}{20} = 0.16$

$x \times \frac{20}{23} = 0.16$

$\frac{20}{23}x = 0.16$

$x = \frac{23}{20} \times 0.16$

$x = \frac{23}{20} \times \frac{4}{25}$

$x = \frac{23}{5} \times \frac{1}{25}$

$x = \frac{23}{125}$

$x = 0.184$

_________

$0.408 \div x = 1.7$

$\frac{51}{125} \times \frac{1}{x} = 1.7$

$\frac{51}{125x} = 1.7$

$51 = 212.5x$

$212.5x = 51$

$x = 0.24$

$x = \frac{6}{25}$

Answer 2

Ответ:

х:1,15=0,16. 0,408:х=1,7

х=0,16•1,15. х=0,408:1,7

х=0,184. х=0,24

0,184:1,15=0,16. 0,408:0,24=1,7
