Answer:
There are infinite number of triplet of three decimals whose product will be 40.
Let A=1.6
B=2.56
Then ,
[tex]C=\frac{40}{1.6 \times 2.56}\\\\C=9.765625[/tex]
Why chosen 1.6 and 2.56 as two numbers because if denominator of fraction has term which contain [tex]2^a,\text{or}5^b,\text{or},2^a \times 5^b[/tex], then the fraction will be terminating decimal.
