Whats the greatest ten you can multiply by 19 to get close to but not go over 684

The desired expression is  19 x (3 tens) = 19  x 30 = 570

So, the greatest ten   = 3 (tens)

Step-by-step explanation:

Let us check each tens.

19 x (1 ten)   = 19 x 10  = 190

19 x (2 tens) = 19 x 20  = 380

19 x (3 tens) = 19  x 30 = 570

19 x (4 tens)  = 19 x 40  =  760

But, here 760 is OVER the given term 684.

and 570 is the nearest value to the value 684.

So, the desired expression is  19 x (3 tens) = 19  x 30 = 570

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
