After 1/7 what are the next four multiples of 1/7

Andrei [34K]

Answer:

$\boxed{ \frac{ 2}{ 7},\quad \frac{3 }{ 7},\quad\frac{4 }{ 7},\quad\frac{ 5}{7 } }\\$

Step-by-step explanation:

You find the multiples of a number by multiplying it by successive integers.

For example, to find the multiples of 2, you multiply 2 by 1, 2 by 2, 2 by 3, etc.

The multiples of ⅐ are

⅐ × 1, ⅐ × 2, ⅐ × 3, ⅐ × 4, ⅐ × 5, ⅐ × 6, …

= ⅐, ²/₇, ³/₇, ⁴/₇, ⁵/₇, ⁶/₇, …

After ⅐, the next four multiples are

$\boxed{ \frac{ 2}{ 7},\quad \frac{3 }{ 7},\quad\frac{4 }{ 7},\quad\frac{ 5}{7 } }\\$

Teresa earns a weekly salary of $925 and a 5% commission on her total sales. Ramon earns a weekly salary of $1250 and a 3% commi

zmey [24]

Answer:

$T = R$

$925 +0.05 x = 1250 +0.03 x$

Subtracting 0.03x from both sides we got:

$925 +0.02 x = 1250$

And now subtracting 925 from both sides we got:

$0.02 x = 325$

And dividing by 0.02 both sides we got:

$x = 16250$

So then we need a total 16250 for the amount of sales in order to have the same amount for Ramon and Teresa at the end of the week

Step-by-step explanation:

For this case we can assume that the total salary for Teresa T is given by:

$T = 925 + 0.05 x$

Where x represent the amount of sales. And similarly for the total salary of Ramon we have:

$R = 1250 +0.03 x$

We want to find what amount of sales, x, will result in each of them earning the same amount for the week and we can set up the following equation:

$T = R$

$925 +0.05 x = 1250 +0.03 x$

Subtracting 0.03x from both sides we got:

$925 +0.02 x = 1250$

And now subtracting 925 from both sides we got:

$0.02 x = 325$

And dividing by 0.02 both sides we got:

$x = 16250$

So then we need a total 16250 for the amount of sales in order to have the same amount for Ramon and Teresa at the end of the week
