Answer:
7/10 of the cake left
Explanation:
Thirty cakes were manufactured in total.
1/5 of the cakes are there. 6 cakes overall, or 1/5 of 30 cakes.
10% of 30 cakes is the number of cakes.
10% can be expressed as 10/100 in fractions and as 0.10 in decimals.
10% of 30 cakes is therefore equal to 0.10 times 30 or 3 cakes.
Total cakes prepared minus total number of cakes left equals 30-6-3.
Thus, there are a total of 21 cakes left.
Out of 30 cakes, 21 remained.
In fracion form, 21 out of 30 is equivalent to 21/30.
By dividing the top and bottom of this fraction by three, we can simplify this expression to get
7 out of 10.
That means he has around 7/10 of the cakes left.
