Determine a reasonable estimate for the amount of flour and sugar combined.

Step-by-step explanation:

If Ellen mixed kg of flour with of sugar together, the reasonable estimate for the amount of flour and sugar combined can be gotten by taking the sum  of both masses of ingredients as shown;

Mass of flour =

MAss of sugar =

Combined masses =

The amount of flour and sugar combined is 17/36 kg

equal to

step-by-step explanation:

207/8 is the right
