Answer: 5.6 cm
Step by Step: I used the same formula as the question before and I got the answer for this question. When solving questions like this, you can work backwards from the problem and then solve
4/5x - 4/10 = 2/20...multiply everything by common denominator 20
16x - 8 = 2
16x = 2 + 8
16x = 10
x = 10/16 which reduces to 5/8 <=
If it is said that the range of the answer should be +/- 10% of the particular value, we have to find out the percentage of that particular value. Therefore 10% of 1.8 is,
1.8 * 10/100 = 0.18
If we add this value to the original value,
1.8+0.18 = 1.98
If we subtract this value from the original value,
<span>1.8-0.18 = 1.62
</span>
therefore the range will be,
from 1.62 to 1.98
