Verified Answer :


4L - 2L = 2L

710mL - 690mL = 20mL

your final answer is... 2L  20mL

Answer:

\(2L\) and \(20mL\), or \(2020mL\)

Step-by-step explanation:

We can solve this problem in two ways:

  • Making operations with liters and milliliters separately
  • Converting all measurements to the same unit and subtracting

With the fist way:

\(4L-2L=2L\)

and

\(710mL - 690mL= 20mL\)

anwer is \(2L\) and \(20mL\) wich is the same as \(2020mL\)

With the second way:

Fist conveting everything to mL \(4L =4000mL\)

thus:

\(4L+710mL =4000mL+710mL=4710mL\)

and \(2L=2000mL\)

thus:

\(2L+690mL=2000mL+690mL =2690mL\)

and then subtracting the two values:

\(4710mL - 2690mL= 2020mL\)
