Answer:
PEMDAS
Step-by-step explanation:
First you do the numbers in the parentheses and the exponents
Then you do any multiplication or division in the problem.
Finally, you do any addition or subtraction in the problem.
*All of this should be done from left to right
What must be subtracted from each term of the ratio 3:7 so that the ratio becomes 2:5?
My attempt: Let two numbers be 3x and 7x. So, 3x−y7x−y=25⟹15x−5y=14x−2y⟹y=x3. But the answer is given as 13 only.
I wish somebody could provide some clarifications.
