Here is 2-2/3 x 3/5.
To find the product, we need to multiply a mixed number by a fraction.
To solve this problem, we first need to convert the mixed number to an improper fraction.
Let’s write the mixed number where we can have some space to work with it.
There is a denominator of 3 alongside the whole number 2.
3 x 2 = 6. The whole number 2 is equal to 6/3.
And, here are 2 more thirds.
6/3 + 2/3 = 8/3
2-2/3 = 8/3
Now, we will multiply this by 3/5.
What is 8 x 3? 24
