Answer:
1/12 of the original amount
Step-by-step explanation:
All you need to do is multiple 1/3 (the fraction left over) by him and his friends (4).
1/3x1/4=1/12
You make 4 into 4/1 and then flip it making it 1/4 since we are dividing.
The final answer is 1/12.
Let one no. be x , Then according to question other number will be 8x
Now 8x - x = 70
7x = 70
x=10
hence one no is 10 and other 80
The answer is Y=10x-3 if that’s the type of equation you wanted.
7n-13=5n+7
7n-5n=7+13
2n=20
n=20/2
n=10
