Method 1)
____________________________
(4/5) *(20/1) = ?
The "5" cancels to a "1" ; and the "20" cancels to a "4" ;
(since "20÷5=4" ; and "5÷5=1") ;
________________________________
Rewrite as: (4/1) * (4/1) = 4 * 4 = 16.
_________________________________
Method 2)
_______________________________
4/5 * 20/1 = (4*20)/(5*1) = (80/5) = 16 .
_________________________________
Method 3)
_________________________________
4/5 * 20 = ? ;
4/5 = 8/10 = 0.8 ;
0.8 * 20 = 16.0 = 16.

There are 6 girls who wear glasses in the class, so the remaining must be the boys. 14-6=8 so there must be 8 boys who were glasses
The answer is 42 ft 4 in
The perimeter of a rectangle with length l and width w is:
P = 2l + 2w
l = 12 ft 3 in
w = 8 ft 11 in
1 ft = 12 in
l = 12 * 12 in + 3 in = 144 in + 3 in = 147 in
w = 8 * 12 in + 11 in = 96 in + 11 in = 107 in
P = 2 * 147 + 2 * 107 = 294 + 214 = 508 in
P = 508 in = 504 in + 4 in = 42 * 12 in + 4 in = 42 ft 4 in
