Yes because $18 divided by 3 bracelets makes the price per bracelet $6. $30 divided by 5 bracelets makes the price per bracelet $6. The cost per bracelet is the same so the cost to bracelet ratio is the same and both are a $6 to 1 bracelet ratio
Are you sure you put this right?
None of those are prime numbers.
Exact form: 3336711069/389
Decimal form: 8577663.42 (rounded)
Mixed number form: 8577663 & 162/389
Step-by-step explanation:
Let H = HCF(A,B) and L = LCM(A,B)
Then A*B = L*H
Here L*H = 100*5 = 500
Also H <= A ,B <= L
So we need to find all A*B = 500, satisfying the above condition. This can be done using prime factorisation of 500.
Here 500 = 2^2 * 5^3
so possible values of A and B are
1 , 500
2, 250
4, 125
5,100
10,50
20,25
(assuming order doesn’t matter.)
so pairs satisfying given condition are → (20,25) and (100,5)
You can write a computer program in language of your choice to do it for other bigger numbers.
Solving this kind of problem is easier if you take steps to make the coefficient of the unknown a positive one. Adding 0.6r to both sides makes the coeff. of r a positive one: 0.6r greater than or equal to 2.9+1.3.
0.6r then is equal to or greater than 4.2. Divide both sides by 0.6 to isolate r:
r greater than or equal to 7.
Let r be represented by the horizontal number line. Darken r = 7 and also darken the r axis to the right of r=7.
