Paul weighed two postcards before mailing them they weight 4/10 of an ounces and 42/100 how many what is the total wight of the postcards?

Respuesta :

the answer is 82/100 because if instead of 42/100 was 40/100 4/10 would be equal so it would look like this 40/100+40/100 plus that 2 equals 82/100
