Question

Значение выражения наиболее удобным способом 1,25*2,34+4,46*1,25=7,12*13,9-7,12*3,4=0,47*6,32+6,32*0,53=

Answer 1

1,25*2,34+4,46*1,25=1,25*(2,34+4,46)=1,25*6,8=8,5
7,12*13,9-7,12*3,4=7,12*(13,9-3,4)=7,12*10,5=74,76
0,47*6,32+6,32*0,53=6,32*(0,47+0,53)=6,32*1=6,32

Answer 2

1,25 * 2,34 = 2,925

4,46 * 1,25 = 5,575

7,12 * 13,9 = 99,008

7,12 * 3,4 = 24,208

0,47 * 6,32 = 2,9744

6,32 * 0,53 = 3,3496

To calculate the expression:

1,25 * 2,34 + 4,46 * 1,25 = 2,925 + 5,575 = 8,5

7,12 * 13,9 - 7,12 * 3,4 = 99,008 - 24,208 = 74,8

0,47 * 6,32 + 6,32 * 0,53 = 2,9744 + 3,3496 = 6,324

Therefore, the value of the expression is 8.5, 74.8, and 6.324, respectively.
