one candy bar contains 220 calories. If this represents 10% of the total calories a person consumes in one day, find the total number of calories consumed in a day.
220/x=10/100
cross multiply
so x=2200
is this correct?
thanks
Right.
Yes, your process is correct. To find the total number of calories consumed in a day, you need to set up a proportion using the given information.
Let's assume the total number of calories consumed in a day is represented by 'x' calories. According to the information given, one candy bar contains 220 calories, which is equivalent to 10% (or 10/100) of the total calories consumed in a day.
Setting up the proportion:
Calories in one candy bar / Total calories consumed in a day = 10% / 100%
So, we have:
220 calories / x calories = 10% / 100%
To solve for 'x', we can cross-multiply:
220 * 100% = x * 10%
Simplifying:
220 * 1 = x * 0.1
220 = 0.1x
Dividing both sides by 0.1:
220 / 0.1 = x
x = 2200
Therefore, the total number of calories consumed in a day is 2200 calories. So, your answer is correct!
