If a concrete mix contains 1-1/2 cubic feet of gravel, 1/2 cubic foot of water,
Karolina [17]

Answer:

The correct answer is "50%".

Step-by-step explanation:

The given values are:

Gravel,

= (1-\frac{1}{2} )

Water,

= \frac{1}{2}

Cement,

= 1

Sand,

= 2

Now,

The total mixture will be:

= Gravel+Water+Cement+Sand

By substituting the values, we get

= (1-\frac{1}{2} )+\frac{1}{2} +1+2

= \frac{1}{2} +\frac{1}{2} +1+2

= 4 \ cubic \ feet

hence,

The percentage of sand will be:

= \frac{Sand}{Total}\times 100

= \frac{2}{4}\times 100

= 50%
