Answer:

Step-by-step explanation:

(1x/4 + 1/7) + (3x/8 - 1/3) = x/4 + 3x/8 + 1/7 - 1/3

                                      = x*2/4*2 + 3x/8 + 1*3/7*3 - 1*7/3*7

                                      = 2x/8 + 3x/8 + 3/21 - 7/21

                                      = (2x+3x)/8 + (3-7) /21

                                      = 5x/8 + (-4)/21

                                       = 5x/8 - 4/21

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.
