A bakery made 100 donuts. In the display case,
40/100
were chocolate,
3/10
were glazed, and the rest were cinnamon. Which fraction of the donuts were cinnamon?
43/100
nope. 100-43 = 57 cinnamons
so 57/100
To find the fraction of the donuts that were cinnamon, we first need to determine the remaining fraction after accounting for the chocolate and glazed donuts.
The total number of donuts is given as 100.
The fraction of donuts that were chocolate is 40/100, which simplifies to 2/5.
The fraction of donuts that were glazed is 3/10.
To find the fraction of donuts that were cinnamon, we need to determine the fraction that remains:
1 - (fraction of chocolate + fraction of glazed) = fraction of cinnamon
1 - (2/5 + 3/10) = fraction of cinnamon
1 - (4/10 + 3/10) = fraction of cinnamon
1 - 7/10 = fraction of cinnamon
To simplify the calculation, we can convert 1 to a fraction with the same denominator as 7/10:
10/10 - 7/10 = 3/10
Therefore, the fraction of the donuts that were cinnamon is 3/10.
