Answer: the fraction for number 2 is 5/16, the decimal is 0.3125 this number as a percent is 31.25%
Step-by-step explanation: you're supposed to add all the numbers and the number you're being asked to find the probability of /the 5 nickels they were talking about, you divide 5/16 get 0.3125, then move the decimal over 2 spaces leaving you with 31.25% so number 2 is (fraction: 5/16, Decimal: 0.3125, percent: 31.25
now if you add one dime 1 quarter and 2 pennies then you have 19 total
so 5/19=0.263 then turn 0.263 into a percent it's 26.3 (slide the decimals over twice)  so now you have ( fraction: 5/19, decimal: 0.263, fraction: 26.3)
