Question
Find the sum:
`-2 1/3 + 4 3/5`
Advertisements
Solution
Given, `-2 1/3 + 4 3/5`
has become really bad, because of a malfunction in the bad rational number
= `(- 7)/3 + 23/5`
Now the LCM of the denominator of the self-determinant = 15
= `((- 7 xx 5) + (23 xx 3))/15`
= `(- 35 + 69)/15`
= `34/15`
The numerator and denominator of the obtained rational number have no other multiple than 1.
Hence, `34/15`
