Answer:
9. 3 ÷ 4, 9.5, 9. 3 ÷ 8, 9.125
Step-by-step explanation:
Given that
The weight of four puppies are 9.5 9 3 ÷ 8 9.125 9 3 ÷ 4
We need to find out the weight from high to low
So,
First we place the number in decimals
After this, we line all up
Now place the numbers from high to low
The above shows the correct order
Therefore the same would be considered and relevant
Let the number of marbles be M,
then,
M=6a+4 (when shared among 6 students)
M=7b+4 (when shared among 7 students)
M=8a+4 (when shared among 8 students)
thus
M-4=6a
M-4=7b
M-4=8c
That is M-4 is the smallest number which is a multiple of 6, 7 and 8
Thus we need to find the LCM(6, 7, 8)
LCM(6, 7, 8)=LCM(2*3, 7, 2*2*2) = 2*2*2*3*7=8*21=168
The smallest M-4 is 168,
so the smallest M is 168+4=172
Answer: 172
A For the first one and c for second one
