We have been given two ratios and we are supposed to compare our ratios whether they are proportional or not.
1. We will reduce our fractions to compare our ratios. Let us simplify each of our given fractions.
Let us divide numerator and denominator with greatest common factor. We can see that 21 is GCF of our ratio.
Now we will simplify our second ratio.
GCF of our fraction is 32. Upon dividing our fraction by 32 we will get,
We can see that our both ratios are similar.
2. Now we will find decimal values of our fractions.
We can see that 
.
Therefore, we can say that our ratios are proportional.
The answer is 4, which is an integer
X should equal 8 because if you add the three numbers they give you. You will get 20 and the whole thing is 28
Subtract 195 by the 25 extra minutes paula ran on saturday. then divide the answer(170) by 2 to get 85 for the number of minutes she ran on sunday. Add the 25 extra minutes to 85 to get the number of minutes she ran on saturday, which will be 110 minutes.
This is the concept of algebra, the percentage of Milk in the 4 cup mixture will be found as follows;
the ratio of milk to mixture after 1 cup was added to 3-cups was:
1/3
the total ratio of milk in the mixture was:
1/3+3/5
=14/15
thus the percentage of milk will be:
14/15*100
=93 1/3%
