a) 476 , 35 × 58 , 47 + 41 , 53 = 476 , 35 × 100 = 47635
b) 139 , 4 + 42 , 004 : 0 , 65 = 181 , 404 : 0 , 65 = 279 , 08

a, 476 , 35 × 58 , 47 + 41 , 53 = 476 , 35 × 100 = 47635
b, 139 , 4 + 42 , 004 : 0 , 65 = 181 , 404 : 0 , 65 = 279 , 08

12 , 02 × y = 84 , 14 → y = 7 y + 34 , 58 = 139 , 4 → y = 104 , 82 52 , 01 − y = 10 , 89 → y = 41 , 12 y : 9 = 6 , 56 → y = 59 , 04


\(\frac{1}{8}\times58,35+0,125\times41+12,5\%\times0,65\)
\(=0,125\times58,35+0,125\times41+0,125\times0,65\)
\(=0,125\times\left(58,35+41+0,65\right)\)
\(=0,125\times100\)
\(=12,5\)
\(\frac{1}{8}\)x 58,35 + 0,125 x 41 + 12,5% x 0,65
= \(\frac{1}{8}\)x 58,35 + \(\frac{1}{8}\)x 41 + \(\frac{1}{8}\)x 0,65
= \(\frac{1}{8}\)x ( 58,35 + 41 + 0,65 )
= \(\frac{1}{8}\)x 100
= 12,5

= ( 25% + 35% + 65% + 75% ) x ( 1 + 2/3 + 4 + 1/3 )
= ( ( 25% + 75% ) + ( 35% + 65% ) ) x 6
= 2 x 6 = 12
\(\left(\frac{1}{4}+35\%+0,65+75\%\right)\)\(x\left(1\frac{6}{9}+4\frac{8}{24}\right)\)
\(=\left(\frac{1}{4}+\frac{7}{20}+\frac{65}{100}+\frac{3}{4}\right)\)\(x\left(\frac{15}{9}+\frac{13}{3}\right)\)
\(=\left(\frac{5}{20}+\frac{7}{20}+\frac{13}{20}+\frac{15}{20}\right)\)\(x6\)
\(=2x6\)
\(=12\)
