Would you divide or substract first in this situation?

Question

If x = 3, y = 4, and z = 5.

y - x
____

z - y

Would I do the subtraction first or would it be like y-x/z-y?

Answer 1

Simplify before you divide in that problem and always remember:

PEMDAS

Parenthesis, Exponent, Multiplication, Addition, Subtraction

There is your order of operations for any other problems you have.

Answer 2

subtract than divide.
4-3/ 5-4 = 1/1 = 1

Answer 3

first you would plug in the numbers so you would get (4-3)/(5-4) then you would subtract and get 1/1 and then divide and you get 1

Answer 4

Subtract first, then divide. You really can't divide this expression without first finding a value for the numerator and for the denominator.

Answer 5

You usually divide before subtracting.

Answer 6

As the numerator and denominator require, carry out the subtractions first, to simplify the fraction:

y - x = 1
z - y = 1

Finally, divide.

Answer 7

subtract both of them first so 4-3=1
then 5-4=1
then divide
1 divided by 1 = 1

Answer 8

From what you've drawn, it would look better like this:
(Y-X)/(Z-Y) - Remember your order of operations - PEMDAS, Parenthesis first.

So, subtract first on the top and the bottom, then divide the results.

(4-3)/(5-4) or (1)/(1) = 1

Hope this helps!

Answer 9

Do both subtractions and then divide the answers.

Answer 10

when you have a fraction, you treat both the numerator (top) and denominator (bottom) as if they were in parentheses. therefore, you would substitute in the values:
((4)-(3))
______

((5)-(4))
then subtract:
1
_

1
then divide:
1
