how do I get the equivalent sets for 35 cents and $6.92?

Question

I am helping my granddaughter do 3rd grade math and I can't figure out these kind of problems

Answer 1

Equivalent sets for 35 cents might be 7 nickels OR 3 dimes and 1 nickel.

for $6.92 might be 27 quarters, 1 dime, and 7 pennies

and of course the possibilities are many for each
