Divide. Estimate to help you

Mathematics
1 answer:
Free_Kalibri [48]3 years ago
7 0

Answer:

21

Step-by-step explanation:

We are to divide the expression

15÷5/7

We can change the sign to a product sign and multiply 15 by reciprocal of 5/7

Reciprocal of 5/7 = 7/5

Multiply with 15

= 15 × 7/5

= 15/5 × 7

= 3 × 7

= 21

Hence the resulting value of the expression is 21

Jennifer has 25 books on her bookshelf. She has 10 fiction books, and the rest are non-fiction books. If Jennifer selects a game
saul85 [17]

Answer:

<h2>3/5</h2>

Step-by-step explanation:

If Jennifer has 25 books on her bookshelf and she has 10 fiction books, the number of non-fiction books she has will be 25-10 = 15 non- fiction books.

Probability is the likelihood or chance that an event will occur.

Probability = Expected outcome of event/total outcome.

Since we want the expression that represents the probability that the book she selects will be a non-fiction book, our expected outcome will be 15(the total non fiction she selected)

The total outcome will be the total number of books i.e 25.

Probability that she elects non fiction book = 15/25

= 3/5
