5 pizza / 6 student = 'Z' pizza / 1 student
Cross-multiply the proportion:
5 pizza-student = 6 Z pizza-student
Divide each side of the equation by 6 pizza-student :
5/6 = Z
Each student gets 5/6 of 1 pizza.
It's not so complicated. Cut each pizza into 6 slices,
and each student gets 5 slices.
That's the same as (83 and 1/3) percent of a pizza.
answer= 1
5 x 2 - 3^2
1. First simplify exponents
= that is nine
2. Then Do 5 x 2- 9
5 x 2=10
10-9
= 1
<span>A common factor is a factor of 2 or more numbers.
the factors of 12 are: 1,2,3,4,6,12
the factors of 21 are: 1,3,7,21
1 and 3 are both common factors of 12 and 21.</span>
Answer:
Therefore the sum of three odd numbers is always an odd number. Hence Proved. Let the number is 15,13 and 3 then 15=2*7+1 13=2*6+1 3=2*1+1 where 1,6 and 7 now 15+13+3=2*7+1+2*6+1+281+11 =2(7+6+1)+3 =2*14+3(24 is our 'm') and 2*14≠30. OR 15+13+3≠30
Step-by-step explanation:
The question is that you cannot get 30 by adding any three odd numbers because addition of 3 odd numbers always give another odd number and hence 30 which is an even number cannot be achieved. 2n-1 where n is a natural number.
