Tom has $15.86 to buy marbles that cost $1.25 each. He wants to know how many marbles he can buy. What should he do after he divides?
15.86 / 1.25 = 12.69
He can buy 12 marbles.
Drop the decimal
To find out how many marbles Tom can buy, he needs to divide the total amount of money he has ($15.86) by the cost of each marble ($1.25). The division can be done as follows:
$15.86 รท $1.25 = 12.688
Once Tom has completed the division, he should round down the result to the nearest whole number since he cannot purchase a fraction of a marble. Therefore, Tom can buy 12 marbles.
To round down the result, Tom should simply ignore the decimal part and keep the whole number part, which is 12 in this case.
