What is -4/3 on this? Say all that apply (5 stars and brainliest for best answer)
Aleks04 [339]

Answer:

Rational Numbers

Step-by-step explanation:

- An integer in its most simplified form cannot be a decimal nor a fraction, meaning -4/3 nor -0.75 would work.

- A whole number is a number that is either positive or negative but cannot be a decimal in simplified form. -4/3 is -1.333.... which is less than one and negative, meaning it cannot be a whole number due to it obviously being a decimal.

- -4/3  is not a natural number as it is both a decimal and negative.

- -4/3 is not irrational because it repeats when in decimal form.

- -4/3 is rational as in decimal form it repeats and to give more information, rational numbers can be both positive and negative numbers. The 3 that repeats in the decimal form of -4/3 works as a rational number due to this.

Therefore, it would apply to the first square.

Thanks!

During a huge snowstorm in the white mountains last year , it snowed 400 centimeters in one week . How much did it snow in meter
julia-pushkina [17]
4 meters, since 100 centimeters equal 1 meter you'd divide 400 by 4 to get your answer of 4 meters. It's just basic math. Don't get so scared that you'll get your answer wrong and just focus.
