Sort the ratios listed at the right into bins so that equivalent ratios are grouped together:
cestrela7 [59]

Step 1

<u>Find the irreducible fraction in each ratio</u>

<u>case 1)</u>  \frac{40}{64}

Divide by 8 boths numerator and denominator

\frac{40}{64}=\frac{5}{8}

<u>case 2)</u>  \frac{5}{75}

Divide by 5 boths numerator and denominator

\frac{5}{75}=\frac{1}{15}

<u>case 3)</u>  \frac{14}{35}

Divide by 7 boths numerator and denominator

\frac{14}{35}=\frac{2}{5}

<u>case 4)</u>  \frac{24}{64}

Divide by 8 boths numerator and denominator

\frac{24}{64}=\frac{3}{8}

<u>case 5)</u>  \frac{6}{15}

Divide by 3 boths numerator and denominator

\frac{6}{15}=\frac{2}{5}

<u>case 6)</u>  \frac{65}{104}

Divide by 13 boths numerator and denominator

\frac{65}{104}=\frac{5}{8}

<u>case 7)</u>  \frac{66}{176}

Divide by 22 boths numerator and denominator

\frac{66}{176}=\frac{3}{8}

<u>case 8)</u>  \frac{12}{30}

Divide by 6 boths numerator and denominator

\frac{12}{30}=\frac{2}{5}

<u>case 9)</u>  \frac{15}{225}

Divide by 15 boths numerator and denominator

\frac{15}{225}=\frac{1}{15}

<u>case 10)</u>  \frac{6}{16}

Divide by 2 boths numerator and denominator

\frac{6}{16}=\frac{3}{8}

<u>case 11)</u>  \frac{15}{24}

Divide by 3 boths numerator and denominator

\frac{15}{24}=\frac{5}{8}

<u>case 12)</u>  \frac{48}{128}

Divide by 16 boths numerator and denominator

\frac{48}{128}=\frac{3}{8}

Step 2

<u>Sort the ratios into bins</u>

1<u>) First Bin</u>

<u>Ratio=\frac{5}{8} </u>

\frac{40}{64}

\frac{65}{104}

\frac{15}{24}

<u>2) Second Bin </u>

<u>Ratio=\frac{1}{15} </u>

\frac{5}{75}

\frac{15}{225}

<u>3) Third Bin</u>

Ratio=\frac{2}{5}

\frac{14}{35}

\frac{6}{15}

\frac{12}{30}

4<u>) Fourth Bin</u>

<u>Ratio=\frac{3}{8} </u>

\frac{24}{64}

\frac{66}{176}

\frac{6}{16}

\frac{48}{128}

Isabella spends $4.87 on paintbrushes and paint. How many of each item does she buy? Explain how you found your answer
Rina8888 [55]

Answer:Answer: Isabella buys 2 paintbrushes and 3 jars of paint.

Step-by-step explanation:

Isabella can buy together 5 paintbrushes ( p ) and jars of paint ( p ) : j + p = 5, She can`t buy 4 items ( because 4 * $0.99 = $3.96 < $4.87 ) and she also can`t buy 6 items ( 6 * $0.95 = $5.70 > $4.87 ). So: p = 5 - j. Another equation is: 0.95 * ( 5 - j ) + 0.99 j = 4.87, 4.75 - 0.95 j + 0.99 j = 4.87; 0.04 j = 0.12; j = 0.12 : 0.04; j = 3, p = 5 - 3 = 2. We can prove it: 0.95 * 2 + 0.99 * 3 = 1.90 + 2.97 = 4.87.

(Hope this helps!!!!)
