Here, we are given that piper uses 1/5 meter of ribbon to border around a triangle of equal side length. We have to find the expression that describes the side length of the triangle.
Total length of ribbon used = 1/5 meter.
Number of sides of a triangle = 3.
So, length of each side = 1⁄5 ÷ 3.
Hence, the correct option is C.

Here, we are given that a malt shop uses 1/6th of a box of waffle cones. We have to find the number of days for which 5 boxes of waffle cones last.
Number of days 5 boxes last = 5 ÷ 1⁄6
= 5×6
= 30.
Hence, the correct option is B.

Here, we have to divide 5 by 1⁄6.
We have, 5 ÷ 1⁄6
= 5×6
= 30.
Hence, the correct option is C.

Here, we have to divide 6 by ¼.
We have, 6 ÷ ¼
= 6×4
=24.
Hence, the correct option is C.

Here, we have to divide 1⁄6 by 2.
We have,
1⁄6 ÷ 2
= 1⁄6 × ½
= 1⁄12.
Hence , the correct option is A.

Here, we have to divide 2 by 4/7.
We have, 2 ÷ 4⁄7
= 2 × 7⁄4
= 14⁄4.
Hence, the correct option is C.

Here, we have to divide 4 by ¼.
We have, 4 ÷ ¼
= 4×4
=16.
Hence, the correct option is B.

Here, we have to divide 5 by 1⁄6.
We have , 5 ÷ 1⁄6
= 5×6
= 30.
Hence, the correct option is B.

Here, it is given that John has 12 gallons of water to fill buckets and each bucket takes 1/3 gallons of water. we have to find the number of buckets that John can fill.
Let the number of buckets that John can fill be x.
Then, x × 1⁄3 = 12
=> x = 12 ÷ 1⁄3
=> x = 12×3
=> x =36.
Hence, John can fill 36 buckets and the correct option is C.

Step by step solution:
The way to multiply a fraction is by simply multiplying straight across. The product is also supposed to be a fraction so the numerator of the product will be the product of the numerators of the given numbers and the denominator of the product will be the product of the denominators of the given numbers.
In the given question, 
Thus, option (a) is the correct option.

In the given question, 
Now, the product that we have got is not in its simplest form. For that we need to divide both the numerator and the denominator by the HCF [ Highest Common Factor] of both the numbers, i.e., 5 in this question.
Hence, we get .
Thus, the correct option is option (a)

Step by step solution:
Given,
total weight of plums and grapes =  pounds
weight fraction of the plums = 
Thus, weight of the plums = 
= 
=  =  =  (in its simplest form)
Thus, the plums' weight is  pounds.
Thus, option (d) is the correct option.
