First, I will made 4 1/2 into the decimal which is 4.5. Then, I add 6 with 4.5 to find the total fabric that Belinda will buy which is 10.5 in total. As a result, Belinda buys total 10.5 white and red fabrics.
Lets assume the whole pie is 1, that is all fractions added together have to sum 1.
If Victor eats 1/6 out of 5/6, then the rest is 4/6 of the pie, that is the subtraction of those fractions.
Answer:

Step-by-step explanation:
Let the numerator of the fraction=x
Since the denominator of a fraction is two more than the numerator.
Denominator=x+2
The fraction is therefore:

If both numerator and denominator are decreased by six, the fraction becomes:

The simplified result is 
Therefore:

Substituting x=40 into the initial fraction

Therefore, the original fraction is 
Yes this is equal because 3v+v is 4v and if you divide 12v by 3 you also get 4v
2x-2+x+5=90
3x+3=90
-3 -3
3x/3 =87/3
x=29
