Answer:


2L and
20mL, or
2020mL

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
