This means that for every 5 kilograms of fruit, you'll get 3 kilograms of sugar.
----------------
Let's divide 8 into 5 parts. 8/5 = 5/5 + 3/5 = 1.0 + 0.6 = 1.6
----------------
1.6 x 3 = 3 + 1.8 = 4.8
-------------------
This means that within 8 kg of fruit you'll find 4.8 kg of sugar.

Step-by-step explanation:
Answer:
The sample size needed is 2401.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
The margin of error of the interval is:
95% confidence level
So , z is the value of Z that has a pvalue of , so .
Estimate the sample size needed if no estimate of p is available so that the confidence interval will have a margin of error of 0.02.
We have to find n, for which M = 0.02.
There is no estimate of p available, so we use
The sample size needed is 2401.
To decompose a fraction to one whole, there are different methods to use. The fraction can be decomposed either by division, multiplication(if there are more than one fraction), or addition(if there are more than one fractions).
Example:
Given 8/2, decompose by division:
To do this, divide the numerator by denominator
