Question

Simplify using properties 2/5×1/6-1/12+2/5×2/3​

Answer 1

Step-by-step explanation:

2/5*1/6-1/12+2/5*2/3

= 1/15-1/12+2/5*2/3 (2/5*1/6=1/15)

= 1/15-1/12+4/15 (2/5*2/3=4/15)

= 1/15+4/15-1/12

= 1/3-1/12 (1/15+4/15=5/15=1/3)

= 1/4 (1/3=4/12; 4/12-1/12=1/4)

Answer 2

Answer:

Answer

To Verify the following

(−21)×[(−4)+(−6)]=[(−21)×(−4)]+[(−21)×(−6)]

Taking LHS we have

(−21)×[(−4)+(−6)]

=(−21)×[−4−6]

=(−21)×(−10)

=210

Now , Taking RHS we have

[(−21)×(−4)]+[(−21)×(−6)]

=84+126

=210

Hence , LHS = RHS
