1.
$1 + 2 = 3 \: \: 3 - 4 = - 1$
2.
$30 - 10 = 20 - 15 = 5 + 10 = 15$
4.
$12 - 5 = 7$
5.
$1 + 18 = 19 - 11 = 9 + 16 = 25$
6.
$30 - 5 = 25 + 11 = 36$
7.
$- 6$
9.
$1196 + 18 = 1214 + 3 = 1217$
$1217 - 5 = 1212 + 27 = 1239$
$1239 - 38 = 1201$

Jenna saves $3 for every $13 dollars she earns. Vanessa saves $6 for every $16 she earns. Is Jenna's ratio of money saved to mon

We have been given that Jenna saves $3 for every $13 dollars she earns. Vanessa saves $6 for every $16 she earns.

We can compare the ratios of saved money to earned money by Jenna and Vanessa as:

$\frac{3}{13} =\frac{6}{16}$

Let us simplify our equation.

$0.2307692307692308=0.375$

We can see that $0.231\neq 0.375$ , therefore, Jenna's ratio of money saved to money earned is not equivalent to Vanessa's ratio of money saved to money earned.
