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

Answer 1

17/36 kg

Explanation:

If Ellen mixed
`(1)/(4)`kg of flour with
`(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 =
`(1)/(4)kg\\`

MAss of sugar =
`(2)/(9) kg`

Combined masses =
`(1)/(4)+(2)/(9)`

`= (9+8)/(36) \\= (17)/(36)kg`

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