So here first you have to have same denominators to subtract and add.
to make same denominator you have to multiply something to them which meets up to their lowest common multiple (LCM). so here the easiest thing is multiply each denominator to the other but remember you have to multiply them to the numerator too.
3×9/5×9-2×5/9×5
so it becomes
27/45-10/45
17/45
as you cant bring to its simplest form since the answer in a prime no. leave it like that.
Answer:
The answer is "Population: All artifacts discovered in the dig. Sample: The selected 2% of the artifacts".
Step-by-step explanation:
The sampling procedure is just the structure or road map towards choosing a sample, and it influences several other important elements of a survey. It provides a fundamental plan including technique for sample selection, and in this, question community of all the items found throughout the dug, and the population of the Sample is 2% of the objects picked.
Answer:
754.2
Step-by-step explanation:
First of all, we cannot solve the question the way it is. We need to make 0.1 into a whole number. If we move the decimal to the right, once, then it will become the number one.
Of course, what we do to one, we have to do to the other. We move the decimal to 75.42 to the right one. Now it is 754.2
That looks like the answer. The reason is because we are now dividing by one. Something divided by one, will always be itself.
Now we have the answer of 754.2.
