a supplier sells 2 1/4 pounds of mulch for every 1 1/3 pounds of gravel. The supplier sells 172 pounds of mulch and gravel combi
laila [671]

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

To find 19+(11+37), lennie added 19 and 11. then he added 37 to the sum. what property did he use?
Rudiy27
<span>Lennie used associative law of addition.
Associative law of addition doesn’t matter how you group the given numbers to add.

a + (b + c) = (a + b) + c
=> 19 + (11 + 37) or ( 19 + 11) + 37
=>  19 + (48) or (30) + 37
=> 67 or 67</span>
