Question

Find an equivalent percent for 7/10

Answer 1

Answer: 70%

Step-by-step explanation: Since a percent is a ratio that compares a number to 100, we first find a fraction that's equivalent to 7/10 that has a 100 in the denominator.

To do this, we set up a proportion.

$\frac{7}{10} = \frac{n}{100}$

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

700 = 10n

÷10    ÷10

  70 = n

So we can write the fraction 7/10 as 70%.

Answer 2

So, you know that any number with 100 as the denominator will be a fraction. All you have to do is change the 10 you have now to 100. To do that, you have to multiply BOTH numerator and denominator (top and bottom) by 10. That results in 70/100, which is equal to 70%.
The equivalent percent for 7/10 is 70%.
