So, what i noticed is that there is a pattern regarding the grayed blocks. The first one starts off with 2, then 4, then 6. It is adding 2 each time, ex; 2+2+4, 4+2=6. The answer would be that the sixth one would have 12 grayed blocks.
90 grams are equivalent to 0.09 kilograms and 55 grams are equivalent to 0.055.
So 0.09 + 0.055 = 0.145.
0.145 * 12 = 1.74
So 1.74 kilograms of sugar is needed to make 12 crisps.
To solve the problem we must know about the Ratio.
<h2>What is Ratio?</h2>
A ratio shows us the number of times a number contains another number.
The length of the living space, in reality, is 21 meters.
Given to us
- The scale is given as 2 centimeters equals 2.5 meters.
To find
- the actual length of the living space if the length of the scale drawing is 16. 8 centimeters
<h3>Scale ratio</h3>
As it is given that 2 cm on the scale drawing is equal to 2.5 meters in real, therefore, the ratio can be written as

<h3>Length of the living space</h3>
Using the same scale ratio,


Hence, the length of the living space, in reality, is 21 meters.
