Four fifths of 5 2/3 is what number?

(4/5)

Step-by-step explanation:

Two-thirds of the number is (2/3)x. 10 more than two-thirds of the number is (2/3)x +10. Hence the given problem will be (4/5)x =(2/3)x +10.

4  8/15

Step-by-step explanation:

Of means multiply

4/5 * 5 2/3

We need to change the mixed number to an improper fraction

5 2/3 = (5*3 +2)/3 = 17/2

4/5 * 17/3

Multiply the numerators:4*17 = 68

Multiply the denominators: 5*3 = 15

4/5 * 5 2/3 = 68/15

We need to change the improper fraction to a mixed number

68/15 = 4 with 8 left over  

4 8/15
