55 + 5/5
To write four 5s and make them represent 56 you need to write 55 + 5/5. When worked out it becomes 55 + 1 (5/5=1) which equals 56.
4 = 20 / 5
One possibility is 55 + 5*5 = 55 + 25 = 80
55 + 5/5 = 56
It will take four. 2 x 2 x 2 x 7 = 56
The square root of (4 times 4) plus (4 divided by 4)
2 x 2 x 2 x 7
70*(4/5)= 70*0.8= 56 four fifths of seventy is 56
There are four such numbers: 35, 42, 49 and 56.
There are four protons. Also four neutrons and four electrons
5/5=1 Keep this for later. so 2 5s used. Then do 5*5=25, so 5 5s used as 25 has a five in it, now do 1 - 25=24.
