Question

the Hcf of two numbers is 20 their L.c.m is 30 if one of the number is 385 find the other number​

Answer 1

Answer:

HCF=20

LCM= 30

first number (a)=385

second number=b

LCM*HCF=product of two numbers

20*30=385*B

600/385=B

B=1.56(approximate)

But the number shouldn't be in decimal (sorry i didn't know that for sure)

if it shouldn't be in decimal your question is wrong please check that

Answer 2

$\large\underline\bold{ANSWER \huge{\checkmark}}$

$\large\underline\bold{GIVEN,}$

$\dashrightarrow H.C.F\:of\:the\:two\:numbers\:is\:20$

$\dashrightarrow L.C.M\:of\:two\:numbers\:is\:30$

$\dashrightarrow one\:of\:the\:number\:is\:385\: a= 385$

$\large\underline\bold{TO\:FIND}$

$\dashrightarrow Another\:number(b)$

✯FORMULA IN USE,

$\large{\boxed{\bf{ \star\:\: H.C.F \times L.C.M = a\times b \:\: \star}}}$

$\large\underline\bold{SOLUTION,}$

$\dashrightarrow 20\times 30= 385\times b$

$\dashrightarrow 600= 385b$

$\implies b=\cancel\dfrac{600}{385}$

$\implies b= 1.558$

$\large{\boxed{\bf{ \star\:\: b=1.558\:\: \star}}}$
