2/5=m/70
Use cross multiply
70*2=5*m
140=5m
Divided 5 to each side
140/5=5m/5
m=28
Check:
2/5=m/70
Substitute m with 28
2/5=28/70
2/5=4/10
2/5=2/5. As a result, m=28. Hope it help!
I think Jackyn is correct because 1/2 is half, which means it is .50. So 1/4 would be much smaller than .50 except if it was 2/4. The bigger the number is in negative, the smaller the number.
Imagine there are 8 spots on the shelf. Replace the volumes one by one.
The first volume to be replaced could go in any one of the eight spots.
The second volume to be replaced could then go in any one of the seven remaining spots.
The third volume to be replaced could then go in any one of the six remaining spots.
etc
So the total number of ways the eight volumes could be replaced
= 8!
= 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
= 40,320

Answer:
$20.01
Step-by-step explanation:
In 2004–2012, the interest rate is 0.002%. In 2013, it is 0.004%. In 2014–2021, the interest rate is 0.002%. That is, in the 18 years between 2004 and 2021 (inclusive), the interest rate is 0.002% for 17 of them. The effective account multiplier is ...
(1.00002^17)(1.00004^1) = 1.00038006801
Then the account balance is ...
$20 × 1.00038006801 ≈ $20.01
_____
<em>Additional comment</em>
The annual interest earned on $20.00 is $0.0004. If the account balance is rounded to the nearest cent annually, at the end of the 18 years, the balance will still be $20.00. Not enough interest is earned in one year to increase the balance above $20. At the end of the 18 years, the amount of interest earned is 0.76¢ (a fraction of a penny) <em>only if there is no rounding in intervening years</em>.
