Set the third number as x.

(2580+2920+x)/3=3000
2580+2920+x=9000
5550+x=9000
x=3500

The third number is 3500

likoan [24]

Answer:

Step-by-step explanation:

We turn that upside-down

86 '? '88 '89 '90 '9I

Then obviously we can tell that ? is to be replaced by 87

86 '87 '88 '89 '90 '9I

Then we turn it back right-side up again, and we have:

I6, 06, 68, 88, L8, 98

Answer: L8

Priya has a piece of string 5/6 yard long. She cuts 3/5 of the piece of string for a craft. What is the length of the string lef

Solnce55 [7]

Total length of the string = $\frac{5}{6}$ yard

Length of string used for craft = $\frac{3}{5}$ of total length of string

= $\frac{3}{5}$ of $\frac{5}{6}$

= $\frac{3}{5} \times \frac{5}{6}$

= $\frac{3}{6}$ yard

Length of the string left after use = Total length of the string - Length of string used for craft

Length of the string left after use = $\frac{5}{6}-\frac{3}{6}$

= $\frac{2}{6}$

Reducing it to the lowest term, we get

= $\frac{1}{3}$ yard

Therefore, the length of string left is $\frac{1}{3}$ yard.
