When you are looking for a fraction, it is best to convert this into a percentage, which in this case, is 80%. Following on from this, you will have to round the number up, which in this case, will be to 200- however, depending on the number, this could be different. From this, you then have to find 80% of 200. From this, you then have to divide 200 by 10, giving you 20, and then multiply this by 8, to get 160, and this is a good estimate for 4/5 of 192. Hope this helps you <span />
Answer:
Sum of cubes identity should be used to prove 35 =3+27
Step-by-step explanation:
Prove that : 35 = 8 +27
Polynomial identities are just equations that are true, but identities are particularly useful for showing the relationship between two apparently unrelated expressions.
Sum of the cubes identity:

Take RHS
8+ 27
We can write 8 as
and 27 as
.
then;
8+27 = 
Now, use the sum of cubes identity;
here a =2 and b = 3

or
= LHS proved!
therefore, the Sum of cubes polynomial identity should be used to prove that 35 = 8 +27
