Given :
Tammy saved nickels and pennies in a jar the ration of nickels to pennies was 2 : 5 .
To Find :
If there where 70 nickels in the jar how many coins are there in all.
Solution :
Let, number of pennies are x.
It is given that ratio of nickels to pennies is 2 : 5.
[tex]\dfrac{2}{5} = \dfrac{70}{x}\\\\x = \dfrac{70\times 5 }{2}\\\\x = 175[/tex]
So, numbers of pennies are 175.
Therefore, total number of coins in the jar is, 175 + 70 = 245 coins.
