Question

1) 1,2 · 3,5 − 0,25 · 0,02=2) 1,01 · 6,2 · 100=3) 0,4 · 1,8 · 6,25=​

Answer 1

Ответ:

1)=4,2-0,005=4,195

2)6,262•100=626,2

3)0,72•6,25=4,5

Answer 2

1. To calculate this expression:

1,2 * 3,5 - 0,25 * 0,02

First, perform the multiplications:

1,2 * 3,5 = 4.2 0,25 * 0,02 = 0.005

Now, subtract the second result from the first:

4.2 - 0.005 = 4.195

Therefore, the result is 4.195.

2. To calculate this expression:

1,01 * 6,2 * 100

Multiply the first two numbers:

1,01 * 6,2 = 6.262

Finally, multiply the result by 100:

6.262 * 100 = 626.2

Therefore, the result is 626.2.

3. To calculate this expression:

0,4 * 1,8 * 6,25

Multiply the first two numbers:

0,4 * 1,8 = 0.72

Finally, multiply the result by 6,25:

0.72 * 6,25 = 4.5

Therefore, the result is 4.5.
