The answer is 12. Explanation: You have 30 coins. If you take 30 coins and put them into piles of 5coins each, you will get 6 piles. Take 2 of those piles and you will have 12 coins.
30 / 5 = 6 x 2 = 12
With US coins, a half-dollar and two nickels, or two quarters and a dime. If you have 20-cent coins, 3 of those, or the 50 cent and two 5 cent coins.
160 quarters 4 quarters = 1 dollar 160 quarters = 40 dollars
OK, so you do 7x4 (seven is the main number, and 4 quarters are a whole). The answer to 7x4 is 28. Then in a half there are 2 quarters, so you add 2 to 28 which is 30
42
7.50 divided by 0.25 = 30
25
30 quarters equals $7.50 42 dimes equals $4.20 That adds up to 72 coins with a value of $11.70
One estimate places to total number of coins in circulation at about 30 billion.
70 - 30 = 40, 40/2 - 20, so there are 20 dimes and 50 quarters
3 x quarters = .75 1 x peso = .08 (You didn't specify U.S. coins) 26 x pennies = .26 = 1.09
With US coins, a half-dollar and two nickels, or two quarters and a dime. If you have 20-cent coins, 3 of those, or the 50 cent and two 5 cent coins.
160 quarters 4 quarters = 1 dollar 160 quarters = 40 dollars
Percentage compares two numbers, for example, if you have 30 coins and 15 of them are quarters, then 50% of your coins are quarters. If you just give me one number, such as 4.0, that is not a percent unless you can give me another number to which 4.0 is to be compared.
OK, so you do 7x4 (seven is the main number, and 4 quarters are a whole). The answer to 7x4 is 28. Then in a half there are 2 quarters, so you add 2 to 28 which is 30
the simplest form of 18 and 30 is 3-5ths
If you start with 30 nickels, you have $1.50. Every time you replace a nickel by a quarter, you gain 20 cents. $4.10 is $2.60 more than $1.50, so you need 13 quarters, leaving 17 nickels. Check: 13*0.25 + 17*0.05 = 3.25 + 0.85 = 4.10.
30 of them.
