Let's do the work shall we....

this is going to be a ratio problem.


Striped Marlin:
70 miles/ One hour (Or 60 minutes)

Sailfish:
40 miles/ 30 minutes.

Since 30 minutes is only one half of 60 minutes, all we have to do is multiply the sailfish ratio by 2 in order to receive the correct mph.

(40miles/30 minutes) x2 = (80 miles/60 minutes(or one hour)).

Therefore, the sailfish is faster! 80 miles per hour is faster than the 70 mph marlin.

You convert the minutes to hours and the marlin is slower because 70 mph is less than 80 mph.My work is in the attachment.

Kenzie makes quilts from blue and purple pieces of fabric. The diagram shows the ratio of blue pieces to
REY [17]

The purple pieces are 35 and total pieces is 32 if the Kenzie makes quilts from blue and purple pieces of fabric.

<h3>What is the ratio?</h3>

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

The question is incomplete.

The complete question is in the picture, please refer to the picture.

Total number of pieces = 3+5 = 8

So, the purple pieces = 5(5/8) = 35

Total pieces = 20/(5/8) = 4×8 = 32

Thus, the purple pieces are 35 and total pieces is 32 if the Kenzie makes quilts from blue and purple pieces of fabric.

How to solve 4/7y-2 = 3/7 + 3/14
lisabon 2012 [21]
Solution

1) Simplify \frac{4}{7y}<span> to </span>\frac{4y}{7}
\frac{4y}{7} <span>−2= </span>\frac{3}{7} + \frac{3}{14}

2) Simplify \frac{3}{7} + \frac{3}{14} <span>to <span>914</span>
</span>\frac{4y}{7} <span>−2= </span>\frac{9}{14}

3) <span>Add 2 to both sides
</span>\frac{4y}{7} = \frac{9}{14} <span>+2
</span>
4) Simplify \frac{9}{14&#10;} <span><span>+2</span> to </span>\frac{37}{14}
\frac{4y}{7} = \frac{37}{14}

5) <span>Multiply both sides by 7
</span><span>4y= </span>\frac{37}{14} <span>×7
</span>
6) Simplify \frac{37}{14} <span><span>×7</span> to </span>\frac{259}{14}
\frac{4y}{7} =\frac{259}{14}

7) Simplify \frac{259}{14}<span> to </span>\frac{37}{2}
\frac{4y}{7} = \frac{37}{2}

8) <span>Divide both sides by 4
</span>y= \frac{37}{2} <span>×4
</span>
9) <span>Simplify <span>2×4</span> to 8
</span><span>y=</span>\frac{37}{8}
<span><span>
