We first write the fractions in their decimal forms and find out the ratio.
2 1/4 is equivalent to 2.25, and 1 1/3 is equivalent to 1.33
Ratio will be 2.25 / 1.33 = 1.69 or 1.7 rounded off. Since it cannot be simplified further, then the ratio of mulch to gravel will be 1.7: 1
Quantity of mulch sold → 1.7/2.7 of 172 →0.629 ×172 = 108.2 pounds
Quantity of gravel sold will be 172 -108. 2 = 63 .8 pounds
I feel like I know the answer, but I'm not quite sure. I don't want to provide incorrect answers, so hopefully someone else can answer the question.
I'm really sorry I can't help you.

Step-by-step explanation:
You must divide these fractions with square roots:
/ 6
= 
= 
= 
Three of given <u>lines</u> form a <u>triangle</u> with <u>measures</u> of two <u>interior angles</u> 
and 
The angle with measure 
is exterior angle of considered triangle.
The measure of exterior angle of triangle is equal to the sum of the measures of two not adjacent interior angles:
