Which fraction is bigger 7/8 or 19/20?

2 answers:

5 0

7/8 already reduced to lowest terms, numerator and denominator have no common prime factors, their prime factorization: 
7 is a prime number and 8 = 23;
19/20 already reduced to lowest terms, numerator and denominator have no common prime factors, their prime factorization: 
19 is a prime number and 20 = 2^2 * 5; (and if you solve it up you'll see for yourself that its 19/20)

So 19/20 is bigger.

What number is 5% of 46?

saveliy_v [14]

46 x 0.05, since 5% = 0.05 (5 / 100 = 0.05)

46 x 0.05 = 2.3

7/12 is 58.33% 
How do we change fractions to percents? 
The steps are too simple. 

First, divide the numerator (the number at the top of the fraction) by the denominator (the number below the fraction). 
In the case above, 7 is the numerator and 12 is the denominator. 

So, 7 ÷ 12 = 0.58333 

Then, multiply the result by 100. 0.5833 x 100= 58.33 

Finally, add the percent (%) sign to the result. 

Therefore, 7/12 is 58.33%.

Solve the equation : 8+10^x=1008

Marizza181 [45]

Hi there.

I'm just going to put the answer for now. I might come back and edit my answer if I figure out how to solve this the long way.

All I did was figure out what exponent you raise 10 to.

10³ = 1000

So, we now have 8 + 10³ = 1008

Edit:

I did it on paper - here it is broken down.

8 + $10^{x}$ = 1008

Subtract 8 from both sides.

$10^{x}$ = 1000

We know that 10³ = 1000

x = 3

A student has a 30% chance of receiving chocolate ice cream for dessert at lunch. A statistics class designs a simulation to app

Nadusha1986 [10]

The count of the sections the class should label as "Chocolate Ice Cream" is 3.

<h3>How to calculate the probability of an event?</h3>

Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.

Then, suppose we want to find the probability of an event E.

Then, its probability is given as

$P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}$

where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.

For the considered case, it is given that:

Probability of an student getting Chocolate Ice Cream for dessert at lunch = 30% = 0.3

The count of the sections the class should label as "Chocolate Ice Cream" should be such that spinner getting "Chocolate Ice Cream" as option should have the probability as 0.3

Let the count of the sections the class should label as "Chocolate Ice Cream" be $x$
