Answer 1

Step-by-step explanation:

Let's the raito be in the form of variable x

flour = 6x

butter = 4x

sugar = x

we have given he uses 160 grams of butter

160 = 4x

160/4 = x

40 grams = x

flour = 6x

6 * 40 grams

240 grams

sugar = x

X = 40 grams

so he uses 240 grams of flour 160 grams of butter and 40 grams of sugar.

Answer 2

Answer:

Let mass of flour = 6x

mass of butter = 4x

mass of sugar =1x

Total mass = 11x

Therfore, According to the question,

$= > 6x +160 + x = 11x \\ = >7x + 160 = 11x \\ = > 160 = 11x - 7x \\ = > 160 = 4x \\ = > x = \frac{160}{4} \\ = > x = 40$

mass of flour,

$6x = 6 \times 40 \\ = 240gm$

mass of sugar

$x = 40gm$
