Write two fractions where the LCD is 20

1 answer:

3 0

Two fractions where the LCD between them is 20 can be 7/20 and 20/40.

I chose these 2 fractions because 7/20 cannot be reduced anymore, but 15/40 can be reduced into 10/20.

The odds of drawing an even chip are $\frac{2}{5}$ .

The odds of drawing an odd chip are $\frac{3}{5}$ .

You multiply the two $\frac{2}{5} x \frac{3}{5} = \frac{6}{25}$ .

Knowing you cannot simplify 6/25 any further, you now have your answer!
