I forgot how to multiply by division and multiplication. It’s been such a long time since I’ve done it i’ve practically forgot h
levacccp [35]

Answer:

First, multiplication:

Multiplication is repeated addition, there's really no way to put it simpler. For example:

4 × 6 = 24 because 4 + 4 + 4 + 4 + 4 + 4 = 24

3 × 3 = 9 because 3 + 3 + 3 = 9

9 × 2 = 18 because 9 + 9 = 18

Multiplication, like addition, can also work backwards, so 6 × 4 is also 24, 2 × 9 is 18, and so on.

I recommend practicing your times tables up to 12 if your remembrance has gotten really bad.

Now division:

Division has the same properties as multiplication, except with subtraction. The difference, however, is that division does not work backwards. It's the same as subtraction.

Here are some examples for division:

6 ÷ 3 = 2 because 6 - 3 - 3 = 0 (3 can be subtracted twice, so the answer is 2)

12 ÷ 4 = 3 because 12 - 4 - 4 - 4 = 0

20 ÷ 2 = 10 because 20 - 2 - 2 - 2 - 2 - 2 - 2 - 2 - 2 - 2 - 2 = 0

I'd recommend practicing your long division if you are struggling.

Hope this helped you! If you have any more questions, send me a friend request and I'll check for more questions every so often. :)

A pond is freshly stocked with 6 brown trout and 18 lake trout. The first fisherman in the area catches and releases a trout. He
Andreas93 [3]

Number of brown trout = 6

Number of lake trout = 18

Total number of trouts = 6+18=24

Probability to catch a lake trout first time = \frac{18}{24}

As the fisherman let the trout go, so probability for the second time is =

\frac{18}{24}

Hence, the probability becomes=

\frac{18}{24}\times\frac{18}{24}=\frac{324}{576}

= \frac{9}{16}

The probability to find the brown trout is \frac{1}{16}

as , \frac{6}{24}\times\frac{6}{24}=\frac{36}{576}

= \frac{6}{96}=\frac{1}{16}
