Answer:

7 937253933/1000000000

Therefore, a2 is divisible by 7 and hence, a is also divisible by7.

This means, that b2 is also divisible by 7 and so, b is also divisible by 7.

Therefore, a and b have at least one common factor, i.e., 7.

But, this contradicts the fact that a and b are co-prime.

Write 14_3 as a mixed number

Vitek1552 [10]

Answer:

if you mean like 14/3. you would divide 14 by 3 which would give you 4 times which would equal 12 so you would have two left over that couldn't be divided by 4 and you have to keep the three so the answer would be 4 2/3. with 4 being the big number and 2/3 being the other half of the mixed fraction
