By what percent will a fraction decrease if its numerator is decreased by 50% and its denominator is decreased by 25%?

%

Step-by-step explanation:

We can use a random fraction with numbers that make this problem easier to calculate. We can start with the fraction (1). If its numerator is decreased by 50% and its denominator is decreased by 25%(75% of it), the new fraction will be , which is the same as 2/3

The percent decrease from 1 to 2/3 is 33.333....% or %.

You can use variables to solve this problem, but I find it easier to start with the fraction for calculation purposes.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
