Answer:
1. 0.472
2. 0.25
Step-by-step explanation:
1. reduce the fraction with 3 = 1\4 + 2\9
write all numerators above the Least common denominator 36 =9 + 8\36
Add numbers = 17\36 and the alternate form is 0.472
2. Divide the numerator and denominator by three = 3 ÷ 3\12 ÷ 3 = 0.25
I can't do the others now I have an exam(sorry)
Answer:
3
Step-by-step explanation:
3^1=3 divided by 8 will give a remainder of 3
3^2=9 divided by 8 will give a remainder of 1
3^3=27 divided by 8 will give a remainder of 3
3^4=81 divided by 8 will give a remainder of 1
3^5=243 divided by 8 will give a remainder of 3
You will notice that 3^n will give 3 when n is odd number and 1 when n is even number
Since n=99 and 99 is an odd number,
Then the remainder is 3
