7.238 divided by 1000 using powers of ten rules? i need solving

7.238 × 10-3

Step-by-step explanation:

1. 3 9/20
2. 1.86
3. 3 63/80 4 1/3 , .35, 2/5
5.2(5x+1)
6. 5f+4s
7. Yes it does because the number of steps the runner will take is 46,145. There is no decimal.
8. She sold more on Tuesday because the decimal 7/9= .777 repeating which is smaller than.85.
9. Yes it is in simplest form
10. No it is not
11. 12 more days

Step-by-step explanation: 1) 3 9/20 As 9/20 = 0.45 → 3+0.45 = 3.45 D

2) 28/15 = 1.86 B

3) 3 63/80 = 3.78

   3 1/5 = 3.2

   3 11/20 = 3.55

This way, 3 1/5

4)1/3 = 0.33

   2/5 = 0.4

This way, 1/3 , 0.35 , 2/5 B

5) 2 is the commom figure. 2(5x + 1) D

6) 3f + 2f + 4s = 5f + 4s (we can sum only equal letters) C

7) Yes, it fits because 138,435/3 = 46,145 which is a round number, no decimals.

8) 7/9 = 0.78

As 0.85 > 0.78 Tuesday

9) Yes, it is because 53 is a prime number, there's no way to make it simpler.

10) 2³ x 4 x 5 is not a prime factorization because 4 is not a prime number. To be a prime factorization

4 = 2² ∴ 2³ x 2² x 5 = 2⁵ x 5

11) We need to find de Least Common multiple which is 12. In 12 says they will do the tasks on the same day

3 , 4 |2

3 , 2 |2

3 , 1 |3

1 , 1

2 x 2 x 3 = 12

wow this question my calculator doesn't even know

Step-by-step explanation:

The answer to 1000 divided by 7.238 is 138.159712628 but you can just round it to 138
