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.
