There are 420 calories in 2 1/4 cans of grape soda. How many calories are in 1 can of soda?
420cal = 2.25 cans
? cal = 1can
To find the number of calories we just do the cross product, so:
420cal x 1can / 2.25cans = ? cal
420cal/2.25cans = 186.6667cal
you have to divide 420 by 2 1/4,, to do this, you must first convert 2 1/4 into improper fraction:
2 1/4 = 9/4
*note that to convert mixed number into improper fraction, multiply the denominator (which is 4) by the whole number (which is 2), then add the numerator (which is 1), thus 4*2 + 1 = 9, but the denominator is still 4, thus it's 9/4,,
then divide:
420 / (9/4)
*to do this, get the reciprocal of 9/4, that is, interchange numerator and denominator:
9/4 --> reciprocal is 4/9
now, the operation becomes multiplication instead of division:
420 * (4/9) = ?
you simplify this.
so there,, :)
Thank you Ivan and Jai.
A medical transcriptionist has a three-drawer file cabinet. One drawer is drawer is 4/5 full, one drawer is 2/3 full, and one drawer is 3/4 full. Can the contents be combined into two drawers? Explain why or why
To find out how many calories are in 1 can of soda, we need to divide the total number of calories by the number of cans consumed.
Let's break down the given information:
- 2 1/4 cans of grape soda have 420 calories.
To find the calories in 1 can, divide the total number of calories (420) by the number of cans (2 1/4).
First, convert the mixed fraction 2 1/4 to an improper fraction:
2 1/4 = (2 * 4 + 1) / 4 = 9/4
Then, divide the total calories (420) by the improper fraction (9/4):
Calories in 1 can = 420 / (9/4)
To divide fractions, invert the divisor and multiply:
Calories in 1 can = 420 * (4/9)
Now, perform the multiplication:
Calories in 1 can = 1680/9
Using division, the final answer is approximately 186.67 calories in 1 can of soda.
