Paul weighed two postcards before mailing them. they weighed 4/10 of an ounce and 42/100 of an ounce.

what is the total weight of the postcards?

38/100 oz

46/100 oz

46/110 oz

82/100 oz

82/100 oz

Step-by-step explanation:

1) first, we need to find common denominators to add

4/10=40/100

42/100=42/100

2)next, we add

40/100+42/100=82/100

the total weight of the postcards is 82/100 oz

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
