In the proof that the sum of rational numbers a/b and c/d , where a, b, c, and d are integers and b and d are non-zero, is a rational number, name the property that states that ad + bc and bd are integers. Enter 1 for option 1, 2 for option 2, and 3 for option 3.
Option 1: Associative Property
Option 2: Closure Property
Option 3: Commutative Property
Option 2: Closure Property
is 4.2 + √36 rational or irrational
The sum of 4.2 and √36 is rational.
The number 4.2 is rational because it can be expressed as a fraction (e.g., 4.2 = 42/10 = 21/5).
The square root of 36, which is 6, is also a rational number because it can be expressed as a fraction (e.g., 6 = 6/1).
When adding rational numbers together, the result is always another rational number. Therefore, the sum of 4.2 and √36 is rational.
What must be true about a/b if c/d and ad+bc/bd are both rational numbers?
Option 1: a/b is rational
Option 2: a/b is irrational
Option 1: a/b is rational
is product of √49 and 1/3 rational or irrational
The product of √49 and 1/3 is rational.
The square root of 49 is 7, which is a rational number.
1/3 is also a rational number.
When multiplying rational numbers together, the result is always another rational number. Therefore, the product of √49 and 1/3 is rational.
