25%
Step-by-step explanation:
The formula that we can use in this problem would be:
$decreased / Original $
So we would have
28-21 / 28
7 / 28
1/4
1/4=25
So, the percent decrease if 25%
102 3/5 steps
The bridge is 307 4/5 m long
Her steps are 3/10 m long
Divide the length of the bridge by the length of her steps
First change the 307 4/5 to 8/10 so we have a common denominator
(307 8/10)/(3/10)
Next change 307 8/10 to an improper fraction
Multiply the whole number by the denominator than add the numerator
(3078/10)/(3/10)=1,026/10
Now divide the numerator by the denominator
1,026/10=102 6/10
Which simplifies to 102 3/5
