Answer:

5 9/20

Step-by-step explanation:

4 7/10 + 6/8

Simplify the fractions by dividing the second top and bottom  by 2

4 7/10 + 3/4

Getting a common denominator of 20

4 7/10 *2/2  + 3/4 * 5/5

4 14/20  + 15/20

4 29/20

4 + 20/20 + 9/20

4+1+9/20

5 9/20

First, you have to find the common denominator.

It is 40.

But if we change the denominator, you have to change the numerator as well.

We multiplied 10 by 4 to get to 40, so we multiply 7 by 4.

\frac{28}{40}

We multiplied 8 by 5 to get to 40, so we do the same to 6:

\frac{30}{40}

Now add them:

\frac{28}{40} +\frac{30}{40}

We get:

58/40

1+18/40 is my answer...

Linda is playing a game where she is trying to draw a diamond from a standard deck of cards. If she doesn't get a diamond, she r
atroni [7]

Answer:

The answer would be 0.2%

Step-by-step explanation:

There's 52 cards in a standard deck of cards and a set of 4 for each different symbol. 100% of the deck would be 52 cards and each deck has 4 suits and each suite has 13 cards and 75% of the cards aren't the diamond Linda is looking for so it would be a slim to none chance on pulling a diamond out of the deck and shuffling the deck each time makes it worse so it gives her like a 0.2% chance of pulling a diamond.

Hope this helps :))
