using appt properties find -2/3into3/5+5/2-3/5into1/6 [ rational numers]
Answers
Answer: 2
Step-by-step explanation:-2/3 x 3/5 + 5/2 -3/5 x 1/6
= ( -2/3 x 3/5 ) + 5/2 - ( 3/5 x 1/6 ) [ property of grouping]
= - 2/5 + 5/2 - 1/10 [ taking LCM as 10]
= [-2 x 2 + 5 x 5 - 1 x 1]/10
= [ -4 +25 -1]/10
= [ -4-1 + 25]/10 [ again grouping of similar terms]
= [ -5 + 25] / 10
= 20/10
= 2
