Felicia drew the pictures at the right to show 3/8 is greater than 3/4. What was Felicia’s mistake?
Alborosie
To show equality with fractions both fractions should be converted to show their values with the same denominator then draw a picture of those fractions.

Remember that you can only compare fractions with the same denominator as is said with other operations dealing with fractions.

Find an inverse of 16 modulo 17. That is solve 16x=1(mod 17)
mote1985 [20]

Answer:

-1 is the inverse of 16 modulo 17.

Step-by-step explanation:

To find : An inverse of  16 modulo 17 i.e. 16x=1(mod 17)?

Solution :

First we find the GCD of (17,16) using Euclid's algorithm,

17=16\times 1+1

Remainder is 1.

Which means, GCD(17,16)=1

Using back substitution we get,

1=17-16(1)

\Rightarrow 16(-1)=1+17(-1)

\Rightarrow 16(-1)=1(\mod 17)

i.e. -1 is the inverse of 16 modulo 17.

On comparing with 16x=1(mod 17)

The value of x=-1.
