A cleaner recommends mixing 1 1/2 cup of cleaner for every 12 cups of water. What is the ratio of cleaner to water.

Anna007 [38]

Answer: $\frac{1}{8}$ or $1:8$

Step-by-step explanation:

First, you can convert the mixed number $1\ \frac{1}{2}$ into a decimal number. To do this, you need to divide the numerator (which is 1) by the denominator (which is 2) of the fraction:

$\frac{1}{2}=0.5$

Now you must add 0.5 to the whole number part. Then:

$1+0.5=1.5$

In order to find the ratio of cleaner to water, you must divide 1.5 cups of cleaner by 12 cups of water.

Therefore, the ratio is:

$ratio=\frac{1.5}{12}=\frac{1}{8}$ or $1:8$

The series formed by using exponential property we get : $\frac{1}{2} , \frac{1}{4} , \frac{1}{8} ,\frac{1}{16} ,\frac{1}{32} ,\frac{1}{64} ,\frac{1}{128} ,\frac{1}{256} ,\frac{1}{512} ,\frac{1}{1024} .$

What is Exponential Property?

Properties of Exponents : It is also called power or degree.
It tells us how many times the base will be multiplied by itself.
The properties of exponents or laws of exponents are wont to solve problems involving exponents.
These properties also are considered as major exponents rules to be followed while solving exponents.

Using exponential property on given values we get,

$2^1=1/ 2\\2^2=1/4\\2^3=1/8\\2^4= 1/16\\2^5= 1/32\\2^6 = 1/64\\2^7 = 1/128\\2^8 = 1/256\\2^9 = 1/512\\2^10 = 1/1024\ ...$

Complete series using exponent property is: $\frac{1}{2} , \frac{1}{4} , \frac{1}{8} ,\frac{1}{16} ,\frac{1}{32} ,\frac{1}{64} ,\frac{1}{128} ,\frac{1}{256} ,\frac{1}{512} ,\frac{1}{1024} ,$
