The solution is:
1 times 20 equals 20
2 times 10 equals 20
4 times 5 equals 20
Here, we have,
given that,
we have to find what times what equals 20.
now, let the numbers be x and y
so, we get, x × y = 20
now, we know that,
the numbers that make 20 are: 1, 2, 4, 5, 10, 20
so, we get,
There can be multiple answers to this question.
as, we have,
20 × 1 = 20
10 × 2 = 20
5 × 4 = 20
Hence, The solution is:
1 times 20 equals 20
2 times 10 equals 20
4 times 5 equals 20

Answer:
43 dimes, 22 nickels
Step-by-step explanation:
n + d = 65....this is just dealing with the total number of coins
0.05n + 0.10d = 5.40....this is dealing with the actual $ amount...nickels are worth 0.05 and dimes are worth 0.10
n + d = 65....n = 65 - d
now we sub that back into our other equation
0.05(65 - d) + 0.10d = 5.40
3.25 - 0.05d + 0.10d = 5.40
-0.05d + 0.10d = 5.40 - 3.25
0.05d = 2.15
d = 2.15 / 0.05
d = 43 <==== 43 dimes
n + d = 65
n + 43 = 65
n = 65 - 43
n = 22 <=== 22 nickels
