Answers
Answer:
(4 x y) x (4 × y) =252
y = sqrt (252/16)= sqrt (15.75)
This is nearly 4
Actually 3.968626967
4 x 3.968626967=15.87450786
252 is in the 7 times table
36 x 7 = 252
So sqrt 36 x sqrt 7 = sqrt 252
= 6 x 2.45751311 = 15.87450787
Notice the last digit is different.
15 squared = 225
16 squared = 256
There are 31 numbers in between these two perfect squares.
252 is nearer to 16 x 16
(16 x y)×(16 × y) = 252
y = sqrt(252/256) = 0.992156741
16 x 0.992156741=15.87450787
28 x 9 = 252
36 x 7 = 252
14 x 18= 252
17.5 x 14.4 = 252
17.5/1.125= 15.555555 15 5/9
14.4 x 1.125 = 16.2
16. 1/5 × 98/100 = 15 219/250
This squared = 252.047376
15 219 × 3 /250 x 3 = 657/750
Reduce the nominator by 1
15 656/750 = 15 328/375
This squared is 252.0050417
Correct to 3 decimal places
Times 656 x 10 = 6560 and 750 x 10= 7500
Take 1 off the nominator = 6559/7500
= 15 6559/7500
This squared = 252.0008086
Correct to 3 decimal places.
The actual answer is a huge fraction
15 87450787/100000000
It is 8745 x 100000= 87450000
Plus 787
= 87450787
So ( 8745/100000 + 78700/100000) + 15
