Question

solve question no.5​

Answer 1

Answer:

we know the formula that HCF multiply LCM = product of two numbers

180 multiply 6 = 30 multiply b

= 180 multiply 6/30 = 6

answer is 36 or b is 36

Answer 2

Answer:

L.C.M= 180

H.C.F=6

NO-1=30

NO-2=?

THEN WE KNOW THAT----

H.C.F.*L.C.M.=NO-1*NO-2

6*180=30*No-2

1080=30*No-2

No-2=1080/30=36

No-2=36
