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

Answer 1

Answer:

17/36 kg

Step-by-step explanation:

If Ellen mixed $\frac{1}{4}$kg of flour with $\frac{2}{9} kg$ 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 = $\frac{1}{4}kg$

MAss of sugar = $\frac{2}{9} kg$

Combined masses = $\frac{1}{4}+\frac{2}{9}$

$= \frac{9+8}{36} \\= \frac{17}{36}kg$

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