Mr. Cline needs 36 ice cubes for the science experiment. Eack ice tray makes 12 ice cubes. If he makes 4 ice trays, does he have enough ice cubes? Can you use an estimate to solve? Explain.
what is 12 x 4 ?
as an estimate what is 10 x 4 ?
(suppose each tray has only 10 cubes)
To determine if Mr. Cline has enough ice cubes, we can use estimation.
First, let's find out how many ice cubes Mr. Cline can make with 4 ice trays. Since each ice tray makes 12 ice cubes, we multiply 12 by 4: 12 x 4 = 48.
So, Mr. Cline could make 48 ice cubes using the 4 ice trays.
Since Mr. Cline needs only 36 ice cubes, we can conclude that he has more than enough ice cubes.
To check this, we can compare the actual number of ice cubes made (48) with the required number (36). Since 48 is greater than 36, our estimation confirms that Mr. Cline has enough ice cubes.
So, to summarize, using an estimate helped us determine that Mr. Cline has enough ice cubes because the estimated number of ice cubes (48) is greater than the required number (36).
