eyeyeyeyeyeyeyeyeyeey
the mean (average) of the data set below
2/4, 18/5, 28/10, 5/20
We are given with 4 fraction
to find mean , we add all the fractions and divide by 4
Lets add all the fractions
Make the denominators same
LCM is 20
Try to get 20 in the denominator
Now we divide by 4
Answer:
12.5
Step-by-step explanation:
Average = (numbers added together)/ number of numbers
=(12+13)/ (2)
=25/2
=12.5
Rewrite the fractions as improper fractions:
1. −4 2/5 ÷ (−5)
= -22/5 ÷ −5/1
= -22/5 x -1/5
=22/25
2. −4 4/5÷4
= -24/5 ÷ 4/1
= -24/5 x 1/4
= -6/5
= -1 1/5
3. −2 1/8 ÷ 1 1/4
= -17/8 ÷ 5/4
= -17/8 x 4/5
= -68/40
= -17/10
=-1 7/10
4. −6 7/8 ÷ (−3 3/4)
= -55/8 ÷ -15/4
= -55/8 x -4/15
= 220/40
= 11/6
= 1 5/6
5. −8 3/4÷ 2 1/6
= -35/4 ÷ 13/6
= -35/4 x 6/13
= -210/52
= - 105/26
= -4 1/26
The answer is
3x - 3x - 7
=-7
