please solve the question and write the correct answer please help me I am just like your sister. first first exercise question
7.
Table (i):
Total number of pieces = 6
Number of pieces eaten = 5
Fraction of pizza eaten = [tex]\frac{5}{6}[/tex]
Table (ii):
Total number of pieces = 15
Number of pieces eaten = 11
Fraction of pizza eaten = [tex]\frac{11}{15}[/tex]
Comparing these two fractions,
[tex]\frac{5}{6}[/tex] and [tex]\frac{11}{15}[/tex]
Taking LCM we get,
[tex]\frac{50}{60}[/tex] and [tex]\frac{44}{60}[/tex]
Since 50 > 44,
[tex]\frac{50}{60} > \frac{44}{60}[/tex]
⇒ [tex]\frac{5}{6} >\frac{11}{15}[/tex].
Therefore pizza eaten on Table (i) is more.

Weight of apples bought = [tex]\frac{17}{4} kg[/tex]
Weigh of grapes bought = [tex]\frac{12}{5}kg[/tex]
Total weight of fruits = [tex]\frac{17}{4} +\frac{12}{5} = \frac{5*17+12*4}{5*4} =\frac{85+48}{20} =\frac{133}{20}kg[/tex]

Total length of rope = [tex]\frac{7}{8}m\\[/tex]
Length of rope cut = [tex]\frac{1}4} m[/tex]
Total length = Length of cut + Length of rope remaining
Length of rope remaining = [tex]\frac{7}{8}- \frac{1}{4}=\frac{7}{8}-\frac{2}{8} =\frac{7-2}{8} =\frac{5}{8}m[/tex]
Answer:
7.
Solution
At 1st Table....
Pizza was cut into 6 peices
out of which 5 peices were eaten.
now,
fraction of peices eaten=(5/6)
At 2nd Table...
Pizza was cut into 15 peices
out of which 11 peices were eaten
now,
fraction of peices eaten=(11/15)
To know which one was eaten more, we are gonna convert the fraction into decimal
so,
5/6=0.83
11/15=0.73
clearly, .83>.73
therefore,Pizza was eaten more on table 1..
8.
Total weight of fruits=(17/4)+(12/5)
=(85+48)/20.
=133/20
=6.65kg ans
9.Total lenght of rope = one peice+other peice
now,
let the other peice be x meters
according to question,
7/8=1/4+x
x=(7/8)-(1/4)
x=(7-2)/8
x=5/8 meters ans
Hopefully it helps, sister
Thanks
