I belive it is S=2C. Even if it was three years ago, if Sherman was twice as old then, then he would be twice as old now. So you can get rid of the three years ago. if someone is twice as old, it is the same as doubling it.

zachary has coins of the coins 3/6 are nickles, 2/6 dimes, rest are quarters. What is the ratio of zacharies nickles, to dimes t

lesya692 [45]

Answer:

The ratio of zacharies nickels to dimes to quarters is 3 : 2 : 1.

Step-by-step explanation:

Given:

Zachary has coins of the coins 3/6 are nickels, 2/6 dimes, rest are quarters.

Now, to get the ratio of zacharies nickels, to dimes to quarters.

So, as given dimes and nickels we find the quarters to get the ratio:

$\frac{3}{6} -\frac{2}{6}=\frac{3-2}{6} =\frac{1}{6}$ .

Thus, the quarters are 1/6.

Now, getting the ratio of the coins:

Nickels = 3/6 × 6 = 3

Dimes = 2/6 × 6 = 2

Quarters = 1/6 × 6 = 1

Nickels : Dimes : Quarters = 3 : 2 : 1.

Therefore, the ratio of zacharies nickels to dimes to quarters is 3 : 2 : 1.
