 256 * 40 = 10,240 cm needed

so if the balls are 30 cm each then

10, 240 divided by 30 = 341.3

so the teacher will need 342 balls.

John bought a used truck for $4,500. He made an agreement with the dealer to put $1,500 down and make payments of $350 for the n
lbvjy [14]
<span>The extra cost can be calculated by working out the total he has spent and subtracting the value of the truck. He spends $1500 on a downpayment and (350 x 10 = $3500) on monthly payments, giving him a total outlay of $5000. This means he overspent by $500. $500 interest was paid for 10 months, so at that same rate, $600 would have been paid for 12 months. $600 as a percentage of the cost of the truck minus the down payment ($3000) is 20%. </span>

600% as a decimal and fraction or mixed number
OleMash [197]
Hello there!

Decimal

To convert a percentage to decimal, you move the decimal point 2 places to the left. 600% - 6.0

Fraction
To convert a percentage to a fraction, divide the percentage by 100. 600/100 = 6/1 = 6

Hope this helps! :)
