Question

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-grandmother's age? Do not include units (percent) in your answer

Answer 1

To find the percent of Jenny's great-grandmother's age compared to Jenny's mother's age, divide Jenny's great-grandmother's age by Jenny's mother's age and multiply by 100.

Step-by-step explanation:

To find the percent of Jenny's great-grandmother's age compared to Jenny's mother's age, we need to divide Jenny's great-grandmother's age by Jenny's mother's age, and then multiply by 100. First, let's calculate the percentage:

Percentage = (Great-Grandmother's Age / Mother's Age) * 100

Plugging in the values, we get:

Percentage = (90 / 36) * 100 = 250%

Therefore, Jenny's great-grandmother's age is 250% of Jenny's mother's age.

Answer 2

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 = (n_(M))/(n_(G))* 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 = (36\,yr)/(90\,yr) * 100\,\%`

`x = 40\,\%`

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