2. What are the steps for adding two fractions that have different signs? 100 points

Step-by-step explanation:

I am joyous to assist you anytime.

first, find the LCM between the two fractions, and multiply each fraction by the appropriate factor so that the denominator becomes LCM for both fractions

then, since they have different signs, add the negative numerator to the positive numerator, and their sum would be the final numerator. if the magnitude of the positive number is bigger than the negative number, the final fraction will be positive, otherwise it will be negative

Step-by-step explanation:

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
