We shall represent the given numbers with positive denominators.
3−5,−710,−1115,−1320.
By multiplying both numerator and denominator by −1 we get, 3−5=3×−1−5×−1=−35
Now let's take the LCM of 5,10,15,20 i.e. 60
By multiplying both numerator and denominator by 12 we get, −35=−3×125×12=−3660
By multiplying both numerator and denominator by 6 we get, −710=−7×610×6=−4260
By multiplying both numerator and denominator by 4 we get −1115=−11×415×4=−4460
By multiplying both numerator and denominator by 3 we get, −1320=−13×320×3=−3960
Clearly by comparing the numerators i.e. −44<−42<−39<−36
∴−4460<−4260<−3960<−3660 i.e. −1115<−710<−1320<3−5.
