Question

A cake is made of 300 grams of flour,150 grams of sugar powder, and 0.75 liters of

water. Find the ratio of the floor to the total mass of the mixture.

Answer 1

Answer: 1/4

Explanation:

0.75 liters is the same as 750 grams.

So, the total mass of the mixture is
`300+150+750=1200` g.

This means the ratio is
`(300)/(1200)=(1)/(4)`.

Answer 2

Flour : total mass = 1 : 4

Explanation:

Given ingredients for the cake:

• Flour = 300 g
• Sugar = 150 g
• Water = 0.75 L

First convert the mass of the water to the same SI units as the other ingredients.

1 liter = 1000 g

⇒ Water = 0.75 liters = 750 g

Total mass of the mixture:

= flour + sugar + water

= 300 g + 150 g + 750 g

= 1200 g

Therefore, the flour to total mass ratio is:

⇒ Flour : total mass = 300 : 1200 = 1 : 4
