Find the sum. Write your answer in simplest form. 3/7 + 2/3​
Delicious77 [7]

Answer:

1 2/21

Step-by-step explanation:

We start out with:

3/7 + 2/3

In order to add them together, they must have an equal denominator. An easy way to find an equal denominator is the cross method. We divide 7 by 3 and 3 by 7, giving us a denominator of 21:

3/21 + 2/21

But what about the numerators? You do the same thing as before (multiplying by the other's denominator).  Now we have:

9/21 + 14/21

We add both together (the denominator stays the same) and we get 23. 23/21 is correct but not in simplest form. We remove 21 from the numerator (because it is a whole) and finally get:

1 2/21!

Ivahew [28]

Answer:

The percent change in Nancy height is 10%

Step-by-step explanation:

Given : when Nancy started middle school, she was 60 inches tall. when she started high school, she was 66 inches tall.

We have to find the percent change in her height.

Percentage change is given by the ratio of the difference in old value and new value to the old value times 100

Mathematically written as

Percentage\ change =\frac{new\ value-old\ value}{Old\ value}\times 100

For the given data,

Old value = 60 inches

New value = 66 inches

Thus, the Percentage change is given as,

Percentage\ change =\frac{66-60}{60}\times 100

Simlify, we have,

Percentage\ change =\frac{6}{60}\times 100

Thus, The percent change in her height is 10%
