The minimum daily values (MDVs) for certain foods are given. They are based on
a 2,000 calorie per day diet. Find decimal and fractional notation for the percent notation
A) 1 OUNCE of Tostitos provides 9% of the MDV of Fat.
C)1/2 cup of Campbells New England clam chowder provides 6% of the MDV of iron. Can someone tell me where to begin.
YOu are given the percents. Convert it to decimal percent, and fractions.
example: 14% converts to .14 and 14/100
A percent sign means the parts of 100. So --
9% = 0.09 = 9/100
What do you think the notations are for 6%?
0.06= 6/100
Right!
How would you turn a fraction into a percent example 1 1/3. would it be 1x3=3+1=4 = 0.04%
Identify the rate, base, and amount in each statement or question. Do not solve the exercise at this point.
150 IS 75% of what number? how do youb go about finding the rate and base?
To find the decimal and fractional notations for the percent notations given, you can follow these steps:
A) For the first scenario, we need to find the decimal and fractional notations for 9% of the MDV of Fat in 1 OUNCE of Tostitos.
Step 1: Determine the MDV of Fat in 1 OUNCE of Tostitos.
The MDV for Fat is based on a 2,000 calorie per day diet. Let's assume it is x%.
From the given information, 1 OUNCE of Tostitos provides 9% of the MDV of Fat. So we can set up the equation:
1 OUNCE = 9% of x%
1 OUNCE = 0.09x
Step 2: Calculate the value of x (the MDV of Fat in 1 OUNCE of Tostitos).
To get the value of x, we can isolate it in the equation:
0.09x = 1
x = 1 / 0.09
x ≈ 11.11
Step 3: Convert the decimal notation to percentage notation.
To convert the decimal notation (0.09) to percentage notation, multiply by 100:
0.09 * 100 = 9%
Step 4: Convert the decimal notation to fractional notation.
To convert the decimal notation (0.09) to fractional notation, write it as a fraction:
9/100
Therefore, the decimal notation for 9% of the MDV of Fat in 1 OUNCE of Tostitos is 0.09, the fractional notation is 9/100.
C) For the second scenario, we need to find the decimal and fractional notations for 6% of the MDV of iron in 1/2 cup of Campbell's New England clam chowder.
Step 1: Determine the MDV of iron in 1/2 cup of Campbell's New England clam chowder.
The MDV for iron is based on a 2,000 calorie per day diet. Let's assume it is y%.
From the given information, 1/2 cup of Campbell's New England clam chowder provides 6% of the MDV of iron. So we can set up the equation:
1/2 cup = 6% of y%
1/2 cup = 0.06y
Step 2: Calculate the value of y (the MDV of iron in 1/2 cup of Campbell's New England clam chowder).
To get the value of y, we can isolate it in the equation:
0.06y = 1/2
y = (1/2) / 0.06
y ≈ 8.33
Step 3: Convert the decimal notation to percentage notation.
To convert the decimal notation (0.06) to percentage notation, multiply by 100:
0.06 * 100 = 6%
Step 4: Convert the decimal notation to fractional notation.
To convert the decimal notation (0.06) to fractional notation, write it as a fraction:
6/100 = 3/50
Therefore, the decimal notation for 6% of the MDV of iron in 1/2 cup of Campbell's New England clam chowder is 0.06, the fractional notation is 6/100 or 3/50.
