naomi's fish is 40 millimeters long. her guinea pig is 25 centimeters long. how much longer is the guinea pig than her fish
horrorfan [7]
Hi there!

The correct answer is 6.25 times.

This is how you get there:

1) First off, you are going to need to have the same unit (either cm or mm). I used millimeters for this problem. 25cm=250mm

2) This next part is very easy to get wrong. You need to figure out what you are dividing, and by what. Simply look at the problem. <span><em>"How much longer is the guinea pig than her fish?" </em>This shows what numbers you should be getting. The guinea pig is 250mm long, where the fish is only 40. This means that her guinea pig should be larger. 250÷40=6.25

If you did this problem the other way, you would've ended up with .16. If you put the sizes into perspective, you will notice that this is highly unlikely.

I hope that I have been able to simplify this problem for you!

The total price of a bag of peaches varies directly with the cost per pound. If 3 pounds of peaches cost $3.60, how much would 5
Levart [38]
<h3>Therefore the cost of 5.5 pound of peaches is $ 6.60.</h3>

Step-by-step explanation:

Given , the total price of a bag of peaches varies directly with the cost per pound. If 3 pound of peaches cost $3.60.

Therefore,

{\textrm{beg of peaches}}\propto{\textrm{cost}}

\Leftrightarrow {\textrm{beg of peaches}}= {\textrm{k  cost}}.......(1)      [ k is a constant]

cost = $3.60 when beg of peaches = 3 pounds

3 = 3.60 k

\Leftrightarrow k = \frac{3}{3.60}

\Leftrightarrow k = \frac{1}{1.20}

Therefore the equation (1) becomes

{\textrm{beg of peaches}}=\frac {cost}{1.20}

\Leftrightarrow {\textrm{beg of peaches}}\times 1.20={cost}

When beg of peaches = 5.5 pound

cost = 5.5 \times 1.20

\Leftrightarrow cost = 6.60

Therefore the cost of 5.5 pound of peaches is $ 6.60.
