3 = 1 X 3
7 = 1 X. 7

Therefore LCM = 1 X 3 X 7
LCM = 21

If I times 21 by 2 then I should get another multiple

So 21 X 2 = 42

Hence the two multiples of 7 and 3 below 50 are 21 and 42.

Lubov Fominskaja [6]

Answer:

The percentage of the price of television reduced to <u>20%</u>.

Step-by-step explanation:

Given:

The price of a television was reduced $250 to $200.

Now, to find the percentage of the reduced price of television.

So, to get the reduced amount of television:

Old price = $250.

New price = $200.

Reduced amount = $250 - $200 = $50.

Now, to get the percentage of price reduced:

\frac{Reduced\ amount}{Old\ price} \times 100

=\frac{50}{250}\times 100

=\frac{5000}{250}

=20\%.

Therefore, the percentage of the price of television reduced to 20%.

Marina CMI [18]

Answer:

A red 5 is chosen from the deck. The card is put back into the deck and the a red card is chosen.

Step-by-step explanation:

An independent event is one whose outcome is not dependent on any other event. There are two types of cards in the deck. If a red card is selected it will be from the series 1 - 20, if the card is put back into deck and then again a red card is selected it will be again from the series 1 - 20. This is an independent event since its outcome is same irrespective of the events.
