85% liczby 70,2 ,

135% liczby 15,

1010% liczby 12.

Answer 1

100% - 140

0,5% - X        x=2,8

 

100% - 70,2

85% -  X        x=59,67

 

15 - 100%

x  - 135 %     x=20,25

 

1010% - x

100% - 12     x=151,5

Answer 2

4%liczby 25 =1 bo 4*25/100 i wszedzie jest taka sama zasada czyli

0,5 % liczby 140 = 0,7

85% liczby 70,2 =59,67

135% liczby 15 = 20,25

1010% liczby 12 =  121,2

;D

 

Answer 3

4 % liczby 25
--------------------
25 - 100%
x - 4%

x = 25 * 4%/100%
x = 100/100
x = 1
=================================

0,5 % liczby 140
---------------------

140 - 100%
x - 0,5%

x = 140  * 0,5/100%
x = 70/100
x = 0,7
==============================

85% liczby 70,2
------------------------

70,2 - 100%
x - 85%

x = 70,2 * 85%/100%
x = 5967/100
x = 59,67
================================

135% liczby 15
-------------------

15 - 100%
x - 135%

x = 15 * 135%/100%
x = 2025/100
x = 20,25
================================

1010% liczby 12
---------------------

12 - 100%
x - 1010%

x = 12 * 1010%/100%
x = 12120/100
x = 121,2
==================================
