Which proportion can be used to solve the following percent problem? What is 50% of 70?
A. x/70=50/100
B. x/50=70/100
C. 50/70=x/100
D. 70/x=50/100

Thank you
I was stuck between A and B, So is the answer A?
well, it better come out 35 :)
either A or B will work. They are really the same. A is the one I would use
Thank You..
50% = 50 out of 100.
Yes, the answer is A.
To solve the problem "What is 50% of 70?" we can use a proportion. A proportion is an equation stating that two ratios are equal. In this case, we want to find a proportion that relates the unknown number (x) to 70 and 50%.
The proportion can be set up as follows:
x/70 = 50/100
Now let's compare this proportion to the given options:
A. x/70 = 50/100 - This is the correct proportion.
B. x/50 = 70/100 - This proportion is incorrect because the unknown (x) should be related to 70, not 50.
C. 50/70 = x/100 - This proportion is also incorrect because the unknown (x) should be on the numerator, not the denominator.
D. 70/x = 50/100 - This proportion is incorrect because the unknown (x) should be related to 70, not on the numerator of the fraction.
Therefore, the correct answer is A. x/70 = 50/100.
I hope this explanation helps!
