Пошаговое объяснение:

Вычисли удобным способом

1) 0,369 + (3,7 + 1,631)=3,7+(0,369  + 1,631) = 3,7 + 2 = 5,7

2) 7,314 + 6,742 + 1,258=7,314 +( 6,742 + 1,258)= 7,314 + 8 = 15,314

3) 5,91 + 4,13 + 7,09 + 5,87=(5,91 + 7,09) + ( 4,13 + 5,87 )= 13 + 10 = 23

Answer 2

1. To calculate 0.369 + (3.7 + 1.631), we start by evaluating the innermost parentheses first:

3.7 + 1.631 = 5.331

Now we can substitute this value back into the original expression:

0.369 + 5.331 = 5.700

So, 0.369 + (3.7 + 1.631) equals 5.700.

2. To calculate 7.314 + 6.742 + 1.258, we simply add the numbers together:

7.314 + 6.742 + 1.258 = 15.314

So, 7.314 + 6.742 + 1.258 equals 15.314.

3. To calculate 5.91 + 4.13 + 7.09 + 5.87, we add the numbers together:

5.91 + 4.13 + 7.09 + 5.87 = 23.00

So, 5.91 + 4.13 + 7.09 + 5.87 equals 23.00.
