9/10

SIZIF [17.4K]

Answer: 90%

Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100.

So to write 9/10 as a percent, we need to find a fraction

equivalent to 9/10 that has a 100 in the denominator.

We can do this by setting up a proportion.

So we have $\frac{9}{10} = \frac{n}{100}$ .

Now, we can use cross-products to find the missing value.

So we have (9)(100) which is 900 <em>is equal</em> to (10)(n) or 10n.

So we have 900 = 10n.

Next, dividing both sides of the equation by 10, we have <em>90 = n</em>.

So, 9/10 is equal to 90/100 or 90%.

How do I find the calculated sum of 1/7 and 1/2

Otrada [13]

$\frac{1}{7}+\frac{1}{2}=\frac{1 \times 2}{7 \times 2}+\frac{1 \times 7}{2 \times 7}=\frac{2}{14}+\frac{7}{14}=\frac{2+7}{14}=\boxed{\frac{9}{14}}$

How do you subtract an integer from another integer without using a number line or counters? Give an example.

torisob [31]

If they are two positive numbers, do it normally. If there is a negative and a positive, change it to addition and switch the SECOND integer sign. Only works with two integer…s in a subtraction question.
