Answer:
28
Step-by-step explanation:
Number of coins in the bag ⇒ 84
Give that,
Dimes : Nickels : Pennies
3 : 2 : 1
You can see that, there are 6 parts . ( 3 + 2 + 1 = 6 )
And now let us write the types of coins in fractions.
Dimes ⇒ 
Nickels ⇒ 
Pennies ⇒ 
And now they're asking for the number of nickels.
To find that, you can multiply 84 ( number of coins) by it's fraction ( 2/6).
Let us solve.
84 × 


28
Therfore, there are 28 nickels.
