\(\left(20,13-20,13:11+\dfrac{1}{4}\right):\dfrac{1}{4}\\ =\left(20,13-1,83+\dfrac{1}{4}\right):\dfrac{1}{4}\\ =\left(18,3+0,25\right):0,25\\ =18,55:0,25\\ =74,2\)
(20,13−20,13:11+14):14=(20,13−1,83+14):14=(18,3+0,25):0,25=18,55:0,25=74,2
25 x 20,13 + 4 x 20,13 - 2013 x 20,33 + 2013 x 20,04
= 20,13 x ( 25+4) - 2013 x ( 20,33 - 20,04)
= 20,13 x 29 - 2013 x 0,29
= 20,13 x 100 x 0,29 - 2013 x 0,29
= 2013 x 0,29 - 2013 x 0,29
= 0
a. 20,13 x 84,5 x 20,13
= 20,13 x 84,5 x 20,13 x 1
= 20,13 x ( 84,5 + 1 )
= 20,13 x 85,55
b. 4,5 x 11/5 + 5,5 x 11/5
= ( 4,5 + 5,5 ) x 11/5
= 10 x 11/5
= 22
a]20,13 * 84,5 * 20,13 = 20,13 * 2 * 84,5
= 20,13 * 169
= 3401,97
b] 4,5 * 11/5 + 5,5 * 11/5 = 11/5 * [4,5 + 5,5]
= 2,2 * 10
= 22
