Answer 2

Answer:

Q.3

Let two numbers be A and B.

Then, A x B = LCM(A,B) x HCF(AB) ____i

A x B= 432(given)

And LCM(AB) =72(given)

To find HCF(AB),

From formula i, 432=72 x HCF(AB)

HCF(AB)=432/72

= 6

Q.4

The given numbers are 108,360 and 1296

Greatest number that divides

108,360 and 1296 should be less than 108 = its HCF

Now, HCF : (By prime factorisation method)

1296=2x2x2x2x3x3x3x3

360=2x2x2x3x3x5

108=2x2x3x3x3

Now, common from them:2x2x3x3=HCF=36

Hence,36 is the greatest number that divides

108,360 and 1296.

Q.5

I). - 9 +(-9)=-18

II). -84

Q.6

98+90-(-253)-43

=98+90+253-43______(- - = +)

=441-43

=398 Answer

Is it okay?
