Answer:
Please check the explanation below.
Step-by-step explanation:
As we know that quadruple is basically a fourfold amount or number.
For example,
The quadruple of 6 is 24.
4 x 6 = 24
Similarly, the quadruple of 10 is 40.
4 x 10 = 40
Now, let me solve your query.
Given the expression
2 - 2
as
2-2 = 0
so
we have to determine the quadruple of 0.
i.e.
4 x 0 = 0
Therefore, 0 is the quadruple of 2-2 (or 0).
I hope, it has cleared your concept.
To add fractions you want to make sure that the bottom numbers are the same so we have to make them the same, but we have to make sure that the fractions are unchanged so we get the correct answer
so if we find out what number that 9,7, and 5 can all multiply into. we find that 9 times 7 times 5 or 315 is the number that will work
so to get them to all be over 315, we must multiply each fraction by a form of 1/1 or x/x or (number)/(same numbe as on top)
so 7/9 times (35/35)=245/315
1/7 times (45/45)=45/315
3/5 times (56/56)=168/315
we add them togther
245/315+45/315+168/315=(245+45+168)/315=458/315
this simplifies to 1 and 143/315
Number 9 is 36 because there are 18/40 who feel safe, so it multiplied would be 36. C
