Well first, you gotta change all of them into pennies so it would be easier. 342 pennies = 342 pennies, 62 nickels = 310 pennies, and 12 dimes = 120 pennies. Then you add them up: 342 + 310 + 120 = 772. You move the decimal two places to the left. 772 = 7.72. The answer will be 7 dollars, 72 cents remain.

What is 8.57 in fraction or mixed number as a decimal
aivan3 [116]
To write 8.57 as a fraction you have to write 8.57 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
8.57 = 8.57/1 = 85.7/10 = 857/100

And finally we have: 
8.57 as a fraction equals 857/100
