Answer:
0.67
Step-by-step explanation:
<u>Solution 1</u>
We can work out the initial number by going backwards from the end:
67/1000= 0.067
0.067*100= 6.7
6.7/10= 0.67
<u>Solution 2</u>
(x*10/100)*1000= 67
x/10*1000= 67
100x= 67
x=67/100
x=0.67
P= a+b+c = 76
side a = 2b = 30
side b = b = 15
side c = 2b + 1 = 31
Answer:
6000 steps
Step-by-step explanation:
1/15 +1/10+1/2=2/30+3/30+15/30=20/30=2/3
2/3=12000 steps
1/3=6000 steps
3/3=18000 steps
Her total steps should be 18000 and she has done 12000 steps.
18000-12000=6000 steps
