Rational numbers are closed under addition ,multiplication but not closed under division
Rational number
Closure property
assume two rational numbers say x and y. the results of addition and multiplication operations give a rational number we can say that rational number are closed under addition and multiplication . For example
rational number are not closed under division as 1 and 0 are rational number but 1/0 is not defined but it is closed under addition and multiplication
that is 1+0 = 1 closed under addition
1*0 =0 closed under multiplication
but 1/0 is not defined so it is not closed under division
Hence Rational numbers are closed under addition ,multiplication but not closed under division

Answer:
A) 14/9
Step-by-step explanation:
14 and 9 have no GCFs (Greatest Common Factors), so the ratio is simply 14/9.
Sin^2 + cos^2 = 1
so,
(x/4)^2 + (y/4)^2 = 1
we got rid of t.
