Convert .12 to a fraction and reduce it to lowest terms

3/25

Step-by-step explanation:

Rewrite the decimal number as a fraction with 1 in the denominator

0.12=0.121

Multiply to remove 2 decimal places. Here, you multiply top and bottom by 10^2 = 100

0.12/1×100/100=12/100

Find the Greatest Common Factor (GCF) of 12 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 4,

12÷4/100÷4 = 3/25

Therefore

0.12 = 3/25

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
