Is 1/6 a rational number or a integer number

Explanation:

The integer numbers are not fractions. Integer numbers are the whole numbers (1, 2, 3, 4, 5, ...) which are positive, and their negatives (-1, -2, -3, -4, -5, ...). Zero is also included in the set of the integer numbers, so they are:

The fractions are rational numbers. Per definition a rational number is the ratio of two integer numbers.

The rational numbers include the integer numbers but is a bigger set, i.e. every integer number is a rational number but not every rational numbers are integer. So, 1/6 is an example of an rational number that is not an integer number.

Any fraction that can be simplified to an integer number is an integer (and also a rational number); any fraction that cannot be simplified to an integer is a rational number but not an integer.

b.an increase in a causes b to decrease

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
