John is making shells for his wrong he was 3 shelves for each shells requires a 8 2/3 be of lumber how many feet of lumber does

Reil [10]

Answer: 26 feet.

Step-by-step explanation:he

The exercise is not written clearly. Assuming that it asks to find the amount of lumber (in feet) John needs for 3 shelves, let "x" represents that amount of lumber in feet.

Based on the data provided, you know that one shelf requires $8\frac{2}{3}$ feet of lumber.

You can convert the Mixed number to Decimal number applying these steps:

1. You must divide the numerator of the fraction by the denominator.

2. You must add the result obtained to the Whole number part.

Then you get:

$8\frac{2}{3}=8+0.6667=8.6667$

Knowing this, you can set up the following proportion:

$\frac{8.6667}{1}=\frac{x}{3}$

Finally, you must solve for "x" in order to find its value. This is:

$(3)(8.6667)=x\\\\x=26.0$

the ratio of the number of womens shoes to the number of mens shoes in a shoe store is 12:7. What fraction of the shoes are mens

stira [4]

7/19 are the fraction of men's shoes

explanation + example:

Use the total number as the denominator: 6 + 8 = 14

Use each of the ratio terms as the numerator in a fraction:

6 becomes 6/14

8 becomes 8/14

Reduce each fraction to lowest terms:

6/14 simplifies to 3/7

8/14 simplifies to 4/7

The part-to-part ratio 6 : 8 converts into the fractions:

6/14 = 3/7

8/14 = 4/7
