To make it easier, you can convert 7/20 to a decimal, and as a decimal it is 0.35. 0.42*0.35=0.147, so .42*7/20=0.147.
Answer:
0.147
Step-by-step explanation:
0.42 * 7/20
Well, 0.42 = 42/100. Now we have both numbers as fractions.
We can simplify 42/100 to 21/50
Therefore we have 7/20 * 21/50
To multiply fractions multiply the numerators together and multiply the denominators together.
This gives: 147 / 1000
Which is equal to 0.147
Therefore 0.42 * 7/20 = 0.147
