HCF(3m,161)=23 and LCM(3m,161)=1449 find value of M

69

Step-by-step explanation:

The product of two numbers is equal to the product of their lcm and hcf whre lcm is the lowest common multiple where hcf is the highest common factor, some countries denote it as gcd, greatest common divisor

Here

HCF(3m,161)=23 and LCM(3m,161)=1449

3m*161=23*1449

483m=23*1449

M=23*1449/483=69

Therefore, the value of m is 69

i do not know the answer i am sorry

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
