Jenny's mom is 36 years old. If Jenny's great-grandmother is 90 years old, what percent of Jenny's mother's age is Jenny's great
Serjik [45]

Answer:

The age of Jenny's mom is 40 % of age of Jenny's great-grandmother.  (Input: 40)

Step-by-step explanation:

The percentage needed is calculated by the following expression:

x = \frac{n_{M}}{n_{G}}\times 100\,\%

Where:

x - Percentage of Jenny's mother with respect to Jenny's great-grandmother, measured in percentage.

n_{M} - Age of Jenny's mother, measured in years.

n_{G} - Age of Jenny's great-grandmother, measured in years.

If we know that n_{M} = 36\,yr and n_{G} = 90\,yr, the percentage is:

x = \frac{36\,yr}{90\,yr} \times 100\,\%

x = 40\,\%

The age of Jenny's mom is 40 % of age of Jenny's great-grandmother.

Why is it important to reduce radicals
OleMash [197]
Simplifying radical expressions expression is important before addition or subtraction because it you need to which like terms can be added or subtracted. If we hadn't simplified the radical expressions, we would not have come to this solution. In a way, this is similar to what would be done for polynomial expression.
