When a problem statement tells you the ratio of one kind of item to another, it is often convenient to group the items in that ratio and deal with the groups. Sometimes, there will be a few missing or left over, for example "10 more than 3 times as many." In those cases, you can make an adjustment to the total and still deal with the groups. (Any equations you might write will effectively do this same thing.)
just count by 60's until you get close to 852 and each 60 is 1 bracelet
No, the answer is 2
X=2
This is because if we multiply the number by x which is 2
so DST is 110, and RSD is 44, so that is 154, and if we do it with RST we also get 154
So the correct answer is X=2
B. 1 and 5 are factors of all three numbers :)
it means that u have to ratios that are equivalent in weight meaning 3:3 = 1 and so is 6:6=1
