Answer:
Step-by-step explanation:
Given that :
Time spent = 5/6
Fraction of students graded = 3/5
Amount of time grading 3/5 of students = 5/6 hours
Total fraction of students = 1/1
If 3/5 of students take 5/6 hours
Then, 1/1 of students will take x
Using cross multiplication :
3/5 = 5/6
1 = x
3x / 5 = 5/ 6
3x * 6 = 5 *5
18x = 25
x = 25 / 18
x = 1.38888 hours
The answer is the first chart which would be A
The answer is B.98
180-122=58
58+24=82
180-82=98
Hope it helped
Answer:
A,C and D
Step-by-step explanation:
A: 3x2=6
3x4X=12X
<em>6+12X</em>
C: 5x1=5
5x2X=10X
5+10X+1+2X
<em>6+12X</em>
D: 7x1=7
7x2X=14X
7+14X-2X-1
6+14X-2X
<em>6+12X</em>
