First, add the two measurements up, then subtract it from 8.
3 1/2 + 2 1/3
Convert to improper fractions:
7/2 + 7/3
Convert to denominators of 6:
21/6 + 14/6
Add the numerators:
35/6
Subtract from 8:
8 - 35/6
Convert 8 into a denominator of 6:
48/6 - 35/6
Subtract the numerators:
13/6
Convert to a mixed number:
2 1/6
So 2 1/6 of the board is left.
7,159=s problem A
8,946-7,150=1,796 Problem B
This is reasonable because I did everything step by step Problem C
Problem 1. the answer is 4,307+1,614=5,921
Problem 2. the answer is 5,036-2,149=2,887

120 percent=120/100=60/50=30/25=6/5, So it simplifies to 6/5.
Answer: Number 1 is c=89 ft
Number 2 is b=3 cm
Step-by-step explanation: a²+b²=c²
For number 1, 39 ft is a and 80 ft is b so
39²+80²=c² so 39² is 39x39=1521 and 80² is 80x80=6400 so 6400+1521=7921
7921=c² and the square root of 7921 is 89 so c=89 ft
For number 2, a=1.6 cm and c=3.4 cm so 3.4²-1.6²=b²
3.4² so 3.4x3.4 which is 11.56
1.6² so 1.6x1.6 which is 2.56
11.56-2.56=c² and 11.56-2.56=9
Square root of 9 is 3 so b=3
So number 2 answer is b=3 cm
I hope this helps
