Answer:
The ratios are not equal
Step-by-step explanation:
Let
x ----> the number of dimes
y ----> the number of quarters
we know that
<em> Suri's coin purse</em>
x=6, y=4
The ratio of dimes to quarters is

<em> Martha's coin purse</em>
x=5, y=3
The ratio of dimes to quarters is

Compare the ratios

therefore
The ratios are not equal
