Answer: The price for the computer = $1152
Step-by-step explanation:
Let the first boy = F
Let the second boy = S
Let the price of computer = C
The second boy had 5/ 6 of the money the first had. I.e
S = 5/6 F
Then F = 6/5S ......(1)
The first boy had 7 /8 of the price of the computer. That is
F = 7/8C ....... (2)
Substitute F in (1) into (2)
6/5S = 7/8C
S = 5/6 × 7/8C
S = 35/48C ......(3)
Together they had $696.00 more than they need to pay. That is
F + S = C + 696 ........ (4)
Substitute equation 2 and 3 into 4
7/8C + 35/48C = C + 696
0.875C + 0.729C = C + 696
0.604C = 696
C = 696/0.604
C = 1152 dollars
Therefore, the price for the computer = $1152
All the fractions that you are subtracting have the same denominator so you just subtract the numerator.2/5-1/5=1/5
3/8-2/8=1/8
79-3/9 since you can simplify 3/9 by 3 you get 1/3 you get 79/1-1/3.the common denominator is 3 so you multiply 79/1 by 3 and 1/3 by 1 and then you get 237/3-1/3 and you get 236/3. then you turn it from an improper fraction into a mixed number. 236 divided by and you get 78.6 repeating
