Answer:
<em>d = 6</em>
Step-by-step explanation:
Cross multiply.
2/9 = d/27
9d = 2 * 27
d = 2 * 3
d = 6
You can also think of finding an equivalent fraction. The left fraction has denominator 9. Multiply 9 by 3 to get denominator 27. Now multiply 2 by 3 t get 6. d = 6
The expression written in equivalent form with a common denominator is -1/6
<h3>Adding fractions</h3>
Fractions are written as ratio of two integers. For instance a/b is a fraction.
Given the sum of the fractions shown;
-3/4 and 5/8
Sum = -3/4 + 5/8
Sum = 5/8 - 3/4
Sum = 5-6/8
Sum = -1/8
Hence the sum of the given fraction -1/3 and 5/8 is -1/6
