6/8 is equivalent to 3/4. How can you use this to help you write 6/8 as a decimal?

Alexus [3.1K]

Answer:

0.75 is the answer

Step-by-step explanation:

6/8 is equivalent to 3/4

3 divided by 4 is 0.75

Since 6/8 is equivalent then it is also 0.75

Also 6/8 turn to 3/4 when both the numerator and denominator is divided by 2.

4) $\frac{3m+15}{2} = 22.5$

Multiply by 2 on both sides

3m + 15 = 45

Subtract both sides by 15

3m = 30

Divide both sides by 3

so m = 3

5) $21= \frac{q+35}{8}$

Multiply both sides by 8

168 = q + 35

Subtract both sides by 35

q = 133

6) $14 + \frac{4z}{-11} = 66$

Subtract 14 from both sides

$\frac{4z}{-11} = 52$

multiply by -11 on both sides

4x = 572

Divide both sides by 4

x= 143

7) $\frac{3}{5} c - 6 = 9$

Add 6 on both sides

$\frac{3}{5} c = 15$

Multiply both sides by 5

3c = 75

Divide both sides by 3

c = 25

8) $\frac{t}{-2} + 17 = -9$

Subtract both sides by 17

$\frac{t}{-2} =26$

Multiply both sides by -2

t = -52

9) $-6 = \frac{5p-(-2)}{-7}$

Multiply both sides by -7

42= 5p + 2

subtract 2 from both sides

40 = 5p

Divide both sides by 5

so p = 8

Use the F-scale measurements of tornadoes listed in the accompanying table. The range of the data is 4.0. Use the range rule of

Tcecarenko [31]

Answer:

Within 0.5 of ;

is not ;

Step-by-step explanation:

Given the data:

The actual standard deviation, = 1

;

The range rule of thumb to estimate the value if standard deviation is ;

Estimated standard deviation = Range / 4

The range = (maximum - minimum) values

The estimated standard deviation = 4 / 4 = 1

Hence, the estimated standard deviation is with 0.5 of the actual standard deviation, Thus, the estimated standard deviation is not substantially different from the actual standard deviation.
