Is 2 a Rational Number Is 2 a Rational Number We know that rational numbers are the numbers written in form of a/b where a and b are integers and bâ‰ 0. Also, 2 can be written as 2/1. On comparing we get a=2 and b=1, So, both a and b are integers and bâ‰ 0. The answer for the query that is 2 a rational number is yes, 2 is a Rational Number. Simplify the given equation with the help of distributive property,4/5(6/5 +4/6)? According to distributive law, A(B+C)=AB+BC, So we simplify it as 4/5*6/5 +4/5*4/6, As we know for multiplication we just need to multiply numerator with numerator and denominator with denominator, so the required result will be, 4*6/5*5 + 4*4/5*6, 24/25 +16/30, Know More About How to learn Calculus
Now, for addition as we are seeing numerator of both the numbers is not equal so we just need to take the LCM for equalizing the denominator. LCM of 25,30 will be the least number, multiple of both 25 and 30 that number is 150 or we can also apply the method in which we multiply the denominator of second number to first one and denominator of 1st to second one. So required result will be: 24*6+16*5/150, 144+80/150, 224/150, It can be also simplified as 112/75 Some important points on rational numbers: 1. All the rational numbers are subset of real numbers or we can say all rational numbers lie in real line. 2. Countless rational numbers lie between two rational numbers. 3. There can be infinite numbers of rational numbers between two integers. 4. Any integer can be represented as rational number. 5. Rational numbers are countable numbers as we can easily count them. Rational numbers are very densely populated as I mentioned above that there can be infinite rational number between two integers. Learn More About Free Tutors Online
We can also find many rational numbers between two numbers. We can perform many operations on rational numbers like addition, subtraction, division and multiplication.
