Question

( 18/25 - 7/20 )• 1/37 + 22/75 : 11/12​

Answer 1

Ответ:

$0.33$

Пошаговое объяснение:

$( \frac{18}{25} - \frac{7}{20} ) \times \frac{1}{37} + \frac{22}{75} \div \frac{11}{12}$

решаем по действиям :

$1) \frac{18}{25} - \frac{7}{20} = \frac{18 \times 4}{25 \times 4} - \frac{7 \times 5}{20 \times 5} = \frac{72}{100} - \frac{35}{100} =$

$= \frac{37}{100} = 0.37$

$2) \frac{22}{75} \div \frac{11}{12} = \frac{22}{75} \times \frac{12}{11} = \frac{22 \times 12}{75 \times 11} = \frac{264}{825} =$

$= \frac{8 \times 33}{25 \times 33} = \frac{8}{25} = 0.32$

$3) \frac{37}{100} \times \frac{1}{37} = \frac{37 \times 1}{100 \times 37} = \frac{37}{3700} = \frac{1 \times 37}{100 \times 37} =$

$= \frac{1}{100} = 0.1$

$4) \frac{1}{100} + \frac{8}{25} = \frac{1 \times 1}{100 \times 1} + \frac{8 \times 4}{25 \times 4} = \frac{1}{100} + \frac{32}{100} =$

$= \frac{1 + 32}{100} = \frac{33}{100} = 0.33$
