How do you add #1/3 + 5/12 + 4/5#?

Answer 1

#1/3+5/12+4/5=1 11/20#

To add #1/3+5/12+4/5#, firs convert all denominators to Lease Common Denominator (LCD), which is nothing but Least common multiple of #3#, #12# and #5#. As #3# is a factor of #12#, their LCD is #12# and LCD of #12# and #5# is #12xx5=60# (as nothing is common between them. Hence LCD of #3#, #12# and #5# is #60#.
Hence, converting each denominator of #1/3+5/12+4/5# to LCD,
#1/3+5/12+4/5# = #(1xx20)/(3xx20)+(5xx5)/(12xx5)+(4xx12)/(5xx12)#
= #20/60+25/60+48/60#
= #(20+25+48)/60=93/60=(31cancel93)/(20cancel60)=31/20=1 11/20#
(We have divided #93# and #60# by #3# here to simplify.)

Answer 2

To add fractions with different denominators, you first need to find a common denominator. In this case, the least common multiple (LCM) of 3, 12, and 5 is 60. Then, rewrite each fraction with the common denominator and add the numerators.

1/3 + 5/12 + 4/5 = (20/60) + (25/60) + (48/60) = 93/60

Now, simplify the fraction if necessary. In this case, 93/60 simplifies to 31/20. So, the sum of 1/3, 5/12, and 4/5 is 31/20.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
