You keep dividing until none of the numerator or denominator can't be divisible by anymore numbers. 40 and 64 can be divided by 8, so the fraction would be 5 over 8. 5 and 8 cannot be divided by anymore numbers.
Divide both by their highest common factor.
If you mean: n/5 = 64/40 then the value of n is 8
5/8 x 64 = 40
64 is an integer in its simplest form. You CANNOT simplify it any more.
44/160 you can divide the numerator and denominator by 4: 11/40
27/64 is simplified.
No. The hcf of 51 and 64 is 1.
45/64 is already in its simplest form
1/7
No
no
13/32
8 over 5
The reduced fraction for 40 over 64 is 5/8
64/24 = (8*8)/(8*3) = 8/3
No, it is already simplified.
3/20
