Question

1) -2,9 : 25 +0,26 x (-100) 2) (-12 - 3,7: (-0,4)) x (-1,60) за ранее огромное спасибо!

Answer 1

1)-2,9:25+0,26×(-100)=-26,116
1) - 2,9:25=-0,116
2,9:25=0,116

2)0,26×(-100)=-26
3)-0,116+(-26)=-0,116-26=-26,116

0,116
26,116

2)(-12-3,7:(-0,4))×(-1,60)=4,4
1)-3,7:(-0,4)=37:4=9,25
2)-12+9,25=-2,75
3)-2,75×(-1,60)=4,4

Answer 2

1. Let's solve the first expression step by step:

-2 + 9 : 25 + 0.26 x (-100)

Step 1: Divide 9 by 25 9 ÷ 25 = 0.36

Step 2: Multiply 0.26 by -100 0.26 x (-100) = -26

Step 3: Add -2 and the result from Step 1 -2 + 0.36 = -1.64

Step 4: Add the result from Step 3 and the result from Step 2 -1.64 + (-26) = -27.64

So, the value of the first expression is -27.64.

2. Now, let's solve the second expression step by step:

(-12 - 3.7) : (-0.4) x (-1.60)

Step 1: Subtract 3.7 from -12 -12 - 3.7 = -15.7

Step 2: Divide -15.7 by -0.4 -15.7 ÷ (-0.4) = 39.25

Step 3: Multiply the result from Step 2 by -1.60 39.25 x (-1.60) = -62.8

So, the value of the second expression is -62.8.
