We now that the probability that one randomly selected car will crash in the year is <span>0.047800478.
If a family has three cars, this means that the probability that some of their car will crash in the next year is : 3 * the probability that one randomly selected car will crash = 3 * </span><span>0.047800478. = 0.143401434</span>

Answer:
Percent is 40%
the decimal is .40
Step-by-step explanation:
1/5 = 20%/.20
So if 1/5 is 20% 2/5 should just have 20% more resolving in 40% or .40
-1 17/20 and -1 8/10 can be compared easily if we give them common denominators. If we multiply the second fraction by 2, both fractions will have a denominator of 20.
8 * 2 = 16
10 * 2 = 20
New fraction: 16/20
-1 17/20 vs. - 1 16/20
-1 16/20 (-1 8/10) is greater. (For negative numbers, you can tell which one is greater by determining which one is closest to zero.)
