x = 25
Answer:
Step-by-step explanation:
Length of each ribbon = 5/8 yards
Length of 16 pieces of ribbon = 16* (5/8)
![=16*\frac{5}{8}\\\\=2 * 5 \\\\=10](https://tex.z-dn.net/?f=%3D16%2A%5Cfrac%7B5%7D%7B8%7D%5C%5C%5C%5C%3D2%20%2A%205%20%5C%5C%5C%5C%3D10)
= 10 yards
Answer:
15/2= faction form
7.5= number form
Step-by-step explanation:
use the KCF
Keep Change Flip
Keep the first number which is 3
Change the division to multiplication
Flip the fraction
So basically 3 times 5 over 2
The multiply straight across
Since 3 isn't a fraction it would be 3 over 1
It will automatically be over 1
Answer:
Rate of simple interest charge by bank is 9.125
Step-by-step explanation:
Given as :
The principal = Rs 8000
The amount paid = Rs 8640
The time period = 320 days
Let the rate of simple interest = R
<u>So from simple interest method </u>
Simple Interest = ![\frac{Principal\times rate\times Time}{100}](https://tex.z-dn.net/?f=%5Cfrac%7BPrincipal%5Ctimes%20rate%5Ctimes%20Time%7D%7B100%7D)
∵, Interest = Amount - principal
Or, Interest = Rs 8640 - Rs 8000 = Rs 640
∴ Rs 640 = ![\frac{8000\times rate\times \frac{320}{365}}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B8000%5Ctimes%20rate%5Ctimes%20%5Cfrac%7B320%7D%7B365%7D%7D%7B100%7D)
Or, 64000 × 365 = 8000 × 320 × rate
Or 23360000 = 2560000 × rate
So, rate = ![\frac{23360000}{2560000}](https://tex.z-dn.net/?f=%5Cfrac%7B23360000%7D%7B2560000%7D)
∴ Rate = 9.125
I.e rate of simple interest charge by bank is 9.125 Answer
