Herald was making a recipe that needs 1/2 cup of vegetable oil and 1/8 cup of olive oil. How much oil does it need in all?

zaharov [31]

Answer:

$\frac{5}{8}$ of oil.

Step-by-step explanation:

Firstly, you need to find the LCD (lowest common denominator), this can be done by factoring the denominators and knowing the multiples.

In this case, you can see that 2 is a factor of 8 so we can simply multiply $\frac{1}{2}$ so that the denominator is 8:

8 ÷ 2 = 4

$\frac{1 * 4}{2 * 4} = \frac{4}{8}$

Now the fractions can be added easily:

$\frac{4}{8} + \frac{1}{8} = \frac{4 + 1}{8}$

= $\frac{5}{8}$ of oil.

Hope this helps!
