Answer:
There is only one perfect number between 20 to 30 which is 28.
<h3>Explanation:</h3>
The number 28 is a perfect number because its factors are 1, 2, 4, 7, 14 and 28.
Product means multiply, so the product of 12 and 8 would be written as 12 x 8
Then you want 6 less than that so you need to subtract 6
The equation should look like (12 x 8) - 6
<em>The five equivalent fractions of 4/5 are:
</em>
<em>
4 × 2/5 × 2 = 8/10
</em>
<em>
4 × 3/5 × 3 = 12/15
</em>
<em>
4 × 4/5 × 4 = 16/20
</em>
<em>
4 × 5/5 × 5 = 20/25
</em>
<em>
4 × 6/5 × 6 = 24/30</em>

<em>8 : 10</em>
<em>12 : 15</em>
<em>16 : 20</em>
<em>20 : 25</em>
<em>24 : 30</em>
Answer:
4 days.
Step-by-step explanation:
She gets 4 centimeters done each day. And 16 - 8 = 8. So you just have to double the days since it's the same amount of length and days for each.
