Why is it essential that the rules for order of operations for rational numbers be the same as the order of operations for integers?

Operations on rational numbers are carried out in the same way as the arithmetic operations like addition, subtraction, multiplication, and division on integers and fractions. Arithmetic operations on rational numbers with the same denominators are easy to calculate but in the case of rational numbers with different denominators, we have to operate after making the denominators the same

Step-by-step explanation:

Rational numbers are expressed in the form of fractions, but we do not call them fractions as fractions include only positive numbers, while rational numbers include both positive and negative numbers. Fractions are a part of rational numbers, while rational numbers are a broad category that includes other types of numbers.

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
