Answer:
The numbers are 1, 20, and 21
Step-by-step explanation:
Let n, n+1 and n+2 be the three consecutive numbers.
<u>To find the numbers</u>
It is given that, the sum of 3 consecutive numbers is 60
n + (n + 1) + (n + 2) = 60
n + n + 1 + n + 2 = 60
3n + 3 = 60
3n = 60 - 3 = 57
n = 57/3 = 19
Therefore the numbers are 1, 20, and 21
The numbers are 19,20 and 21
Let
x -----> the first consecutive number
x+1 ---> the second consecutive number
x+2 --> the third consecutive number
we know that
x+(x+1)+(x+2)=60
Solve for x
3x+3=60
3x=57
x=19
so
x+1=19+1=20
x+2=19+2=21
therefore
200
170% of x = 680
Set up an equation:
170/100 • x/1 = 680
1.7 • x = 680
1.7x = 680
x = 400
50% of 400
1/2 • 400 = 200
x^2 + x + 1 - 2x + 5
x^2 - x + 6
4/5
10:100=8:x
x= 100*8/10
x= 80 (80%)
80% = 80/100 = 8/10 = 4/5
