Answer:

8.5

Step-by-step explanation:

The opposite of -8 is 8.

\frac{1}{2}+8

Convert 8 to fraction \frac{16}{2}.

\frac{1}{2}+\frac{16}{2}

Since \frac{1}{2} and \frac{16}{2} have the same denominator, add them by adding their numerators.

\frac{1+16}{2}

Add 1 and 16 to get 17.

If 45.78 ÷ 1.7 is written in long division form as long division set up where 17 is on the outside of the division symbol and 45780 is on the inside so that the divisor is written as a whole number, where should the decimal point be placed in the dividend?


Between the 4 and the 5

Between the 5 and the 7

Between the 7 and the 8

Between the 8 and the 0



Please help ill give brainlest

Answers

The dividend will be 457.80 and divisor will be 17.

The divisor is 1.7
The dividend is 45.78
We want 17 that is on the outside of the division symbol, written as a whole number.
45780 is on the inside of the division symbol.
So, to make 17 whole number, we will multiply it by 10. And we will also multiply 10 to 45.78 making it 457.80.
(multiplying with 10 means shifting decimal to one right place. Multiplying by 1000 means shifting decimal to 3 right places)
Hence, the dividend will be 457.80 and divisor will be 17.

name 5 fractions whose values are between 1/2 and 7/8

Answers

Answer:

 3/4, 4/6, 5/8, 2/3, 6/10

Step-by-step explanation:

The five fractions that provide a range of values between 1/2 and 7/8 are 5/8, 3/4, 11/16, 2/3, and 13/16.

Here are five fractions that lie between 1/2 and 7/8:

5/8: This fraction is greater than 1/2 but less than 7/8. It can be obtained by dividing 5 by 8.

3/4: This fraction is greater than 1/2 and closer to 7/8. It is obtained by dividing 3 by 4.

11/16: This fraction is closer to 1/2 and slightly less than 7/8. It can be obtained by dividing 11 by 16.

2/3: This fraction is greater than 1/2 and closer to 7/8. It is obtained by dividing 2 by 3.

13/16: This fraction is closer to 7/8 and greater than 1/2. It can be obtained by dividing 13 by 16.

These five fractions provide a range of values between 1/2 and 7/8. They demonstrate different proportions and can be used in various contexts where a fraction between 1/2 and 7/8 is required, such as measurement, comparison, or estimation.
