Given:
Elaine has a piece of wire that is 2.16 meters long.
D ikembe has a piece of wire that is 2.061 meters long
To find:
whose piece of wire is longer?
Calculation:
First convert both decimal expressions into like decimals.
Now, Elaine has a piece of wire that is 2.160 meters long.
D ikembe has a piece of wire that is 2.061 meters long
Its clearly visible that 2.160 > 2.061.
Alternative Way:
By comparing numbers at tens place we can see 1 >0 i.e. 2.16 > 2.061.
Elaine's piece of wire is longer.

A swimming pool, in the shape of a rectangular prism, is 50 meters long, 25 meters wide, and 3 meters deep. A liter is the same as 0.001 cubic meters. How many liters of water are needed to completely fill the pool? I understand half of this question. You have to find the volume of the swimming pool by using B x W x H, which is 50 x 25 x 3 = 3,750 meters. What I don't understand is how to covert 750 meters into liters. Help...?
To find liters from meters, multiply the meters by 1000. 1 meter equals 1000 liters. So, the answer would be 375000 from 3,750
Step 1: −27.8 ÷ 1 over 7
Step 2: −27.8 ⋅ 7
Step 3: −194.6

There is no error.
Answer:
D.There is no error.
Step-by-step explanation:
We are given that Jacob is showing his steps to solve the expression
We have to find the error in Jacob steps in which he makes error
Jacob writes his first step
Step:1
Jacob's first step is true.
We know that if we changes divide sign of term into multiply then the the term which is write on right side of divide sign reciprocal. Therefore,
Step:2
Hence, Jacob's second step is right.
Now , we multiply -27.8 with 7 then we get
Step:3
Hence, Jacob's third step is also right.
Therefore, Jacob makes no error in his steps.
Hence, Option D is true.
