PLS HALP- Fill in the blanks-sometimes-always-or never- -Irrational numbers can be expressed by ratio of 2 integers (sometimes-always-or never)
-If a number is a whole number, it is also rational (sometimes-always-or never)
-Rational numbers are also integers (sometimes-always-or never)
-Non-perfect squares are irrational (sometimes-always-or never)
Pls answer correctly ty

I think they are all always.

Step-by-step explanation:

They are called rational because they are the ratio, or quotient, of two integers

numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

If a square root is not a perfect square, then it is considered an irrational number. These numbers cannot be written as a fraction because the decimal does not end and does not repeat a pattern.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
