Answer:
1/5
1. 1/56
2. 1/6
3. 1/65
4. 1/7
5. 1/75
1/8
Step-by-step explanation:
The fractions I gave (1/56, 1/6, 1/65, 1/7, 1/75) are all in between 1/5 and 1/8.
A way to think about this is to add a zero to a denominator of 1/5 and 1/8 and turn them into whole numbers:
1/5 --> 1/50 --> 50
1/8 --> 1/80 --> 80
Then find number between them:
55, 60, 65, 70, 75
Then, turn them into a fraction with a 1 as the numerator and the number as denominators:
1/55, 1/60, 1/65, 1/70, 1/75
This is the process. These numbers are all in between 1/5 and 1/8.
I hope this helps you!
(P.S., I don't think this works with negative numbers, though)
Answer:
X= -3;
Y=78
Step-by-step explanation:
A: X+Y=75
B: 10X+Y=48
B-A: (10X+Y)-(X+Y)=48-75
10X+Y-X-Y= - 27
9X=-27
X= -3;
Now
A is : -3+Y=75
Y=75+3=78
