2 1/8 - 1 2/7 = ?
8*2+1/8 - 7*1+2/7 =
17/8 + 9/7 =
8,7 | 2
4,7 | 2
2,7 | 2
1, 7 | 7
1, 1 | 1_______ 2*2*2*7 = 56
17/8 + 9/7 =
56÷8*17/56 + 56÷7*9/56 =
7*17/56 + 8*9/56 =
119/56 + 72/56 = 191/56
Answer:
191/56
Answer:
14
Step-by-step explanation:
319 / 11 = 29
(Quick Check) 11 x 29 = 319

Answer:
Therefor it is clear that the percentage of first year student like to listen classical music is less than 10 %
Step-by-step explanation:
Given as ;
The total number of first year students in an university = 250
The number of student who like to listen classical music = 12 out of 250
Let x % of student like to listen classical music
So, x% of 250 = 12
or,
× 250 = 12
or, x × 250 = 12 × 100
Or, x =
∴ x = 4.8
I.e the percentage of first year student like to listen classical music is 4.8%
Now, Again
The 10% of the total number of student is
I.e 10% of 250
or,
× 250
Or ,
I.e The 10% of the total number of student = 25
Since 4.8 % of total number of students is 12 and 10% of total number of students is 25
Therefor it is clear that the percentage of first year student like to listen classical music is less than 10 % . answer
