John predicts his football team will score 67 points in the next game. If John's team actually scored 42 points, what was John's
dolphi86 [110]

Answer:

The error percentage was 59.5%

Step-by-step explanation:

John predicts his football team will score 67 points in the next game.

Prediction score = 67

But John's team actually scored 42 points.

Actual scored = 42

We need to find the error percentage of John's using formula.

\%=\dfrac{\text{|Prediction-exact|}}{exact}\times 100

\%=\dfrac{\text{|67-42|}}{42}\times 100

Percentage error =\dfrac{25}{42}\times 100

                             =59.52\%

We need to round off to nearest tenth.

Hence, The percentage error was 59.5%

What is 1/8 subtract 5/8 in simplest form
Mashcka [7]

The fraction 1/8 is alread in the simplest form, so it isn't possible to reduce it any further.

This is a PROPER FRACTION once the absolute value of the top number or numerator (1) is smaller than the absolute value of the bottom number or denomintor (8).

The fraction 1/8 is equal to 1÷8 and can also be expressed in decimal form as 0.125.

How to reduce a fraction

Among different ways simplifying a fraction, we will show the two procedure below:

Method 1 - Divide by a Small Number When Possible

Start by dividing both the numerator and the denomiator of the fraction by the same number, and repeat this until it is impossible to divide. Begin dividing by small numbers like 2, 3, 5, 7. For example,

Simplify the fraction 42/98

First divide both (numerator/denominator) by 2 to get 21/49.

Dividing by 3 and 5 will not work, so,

Divide both numerator and denominator by 7 to get 3/7. Note: 21 ÷ 7 = 3 and 49 ÷ 7 = 7

In the fraction 3/7, 3 is only divisible by itself, and 7 is not divisible by other numbers than itself and 1, so the fraction has been simplified as much as possible. No further reduction is possible, so 42/98 is equal to 3/7 when reduced to its lowest terms. This is a PROPER FRACTION once the absolute value of the top number or numerator (3) is smaller than the absolute value of the bottom number or denomintor (7).

Method 2 - Greatest Common Divisor

To reduce a fraction to lowest terms (also called its simplest form), just divide both the numerator and denominator by the GCD (Greatest Common Divisor).

For example, 3/4 is in lowest form, but 6/8 is not in lowest form (the GCD of 6 and 8 is 2) and 6/8 can be written as 3/4. You can do this because the value of a fraction will remain the same when both the numerator and denominator are divided by the same number.
