Answer:

8 cookies left to be baked

Step-by-step explanation:

<u>Len</u>

Len bakes 1/3 of 30 cookies

To find 1/3 of 30, divide 30 by 3 then multiply by 1:

\implies \frac{30}{3} \times1=10 \times 1=10

Therefore, Len bakes 10 cookies

<u>Sallesh</u>

Sallesh bakes 2/5 of 30 cookies

To find 2/5 of 30, divide 30 by 5 then multiply by 2:

\implies \frac{30}{5} \times2=6 \times 2=12

Therefore, Sallesh  bakes 12 cookies

<u>Cookies left to bake</u>

To calculate how many cookies are left to bake, subtract the found number of cookies Len and Sallesh have baked from 30:

30 - 10 - 12 = 8

So there are 8 cookies left to be baked.

Converting repeating decimals to a fraction
Goshia [24]

Step-by-step explanation:

Step 1:

Let x equal the repeating decimal you are trying to convert to a fraction.

Step 2:

Examine the repeating decimal to find the repeating digit(s).

Step 3:

Place the repeating digit(s) to the left of the decimal point.

Step 4:

Place the repeating digit(s) to the right of the decimal point.

Step 5:

Using the two equations you found in step 3 and step 4, subtract the left sides of the two equations. Then, subtract the right sides of the two equations

As you subtract, just make sure that the difference is positive for both sides.
