Why is 4 tenths not equal to 4 hundredths?

Answer 1

Imagine that you have a pie. If you cut that pie into 10 equal pieces and take four of them, it will be a lot more pie that if you cut the pie into 100 equal pieces and take four of them.

If you cut the pie into 10 pieces, each piece is a tenth of the pie. If you cut the pie into one hundred pieces, each piece will be a hundredth of the pie.

You can really only tell which fraction is greater when they have the same denominator. 4/10 = 40/100. That's ten times greater than 4/100
