One-fourth of a number is 3 more than one-seventh of the same number.
what is the number?

One-fourth of a number is three more than one-seventh of same number.The required number is 28.

Solution:

Let’s assume require number be x

One fourth of a number =

One seventh of a number =

Given that one fourth of a number is 3 more than one seventh of a number

So in other words if we add 3 to one seventh of a number, we will get one fourth of a number.

4(x+21) = 7x  

4x + 84 = 7x

84 = 7x – 4x  

3x = 84  

x = 28

Hence required number is 28.

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!
