Question

Nisbatning noma'lum hadini toping:1) x : 1,2 = 2,5; 2) 1,8 : x = 1,5;​

Answer 1

Ответ:

$1)x:1,2=2,5\\x=2,5*1,2\\x=3\\2)1,8 : x = 1,5\\x=1,8:1,5\\x=1,2$

Answer 2

Ushbu masalani yechish uchun, biz quyidagi o'zgaruvchilarni aniqlaymiz:

1. $x : 1,2 = 2,5$

Bu tenglikda, $x$ ni topish uchun quyidagi formulani ishlatamiz:

$x = 2,5 \times 1,2$ $x = 3$

2. $1,8 : x = 1,5$

Bu tenglikda, $x$ ni topish uchun quyidagi formulani ishlatamiz:

$x = 1,8 \div 1,5$ $x = 1,2$

Shu sababli, berilgan ikki nisbatning noma'lum hadini topganmiz:

1. $x = 3$
2. $x = 1,2$
