Today for maths we were learning about infinite numbers and how fractions & decimals have infinite numbers and ending numbers. So fractions like 1/3 is infinite in decimals because its 0.3333333 and so on while fractions like 1/5 the decimal of it is 0.5 and it doesn’t continue so that is what we learned today for maths.
1/5, 50%, 0.5 is finite (which means limited)
1/3, 0.333333 is infinite (which means never ending)
