Question

Three and seventt-two hundredths subtracted from five eighty-one hundredths in standard form

Answer 1

5.81 -  3.72 = 2.09 

It's like common subtraction only in decimal basically put one decimal over the other and get rid of the decimal point if needed. 

Answer 2

5.81-3.72=2.09

When it ends in "ths" or says "and" it's behind a decimal
