Answer:
1.4049
Explanation;
We are find the product of 0.42, 1.5 and 2.23
Convert the decimals to fractions first
0.42 = 42/100
1.5 = 15/10
2.23 = 223/100
Multiply the fractions together;
= 42/100 * 15/10 * 223/100
= (42*15*223)/(100*10*100)
= 140,490/100,000
= 1.4049
Hence the product of 0.42, 1.5, and 2.23 is 1.4049
