So 72 pencils and 24 calculators
so greates number of identical calculators
this means
what is the biggest number that we can divide 72 and 24 by and get a whole number
this is called the GCM or greatest common multipule
to find the GCM, you factor 72 and group the like ones
72=2 times 2 times 2 times 3 times 3
24=2 times 2 times 2 times 3
so the common group is 2 times 2 times 2 times 3 or 24
so the greates number of packs is 24
so pencils
72 divided by 24=72/24=3
3 pencils per pack
24 divided by 24=24/24=1
1 calulator per pack
answer is 3 pencils and 1 calculator per pack
Answer:
2 2/3 hours
Step-by-step explanation:
1/4 + 2/3 + 1 3/4 common denominator is 12
3/12 + 8/12 + 21/12 = 32/12 = 2 8/12 = 2 2/3 hours
Answer:
(36 - 10) (divide sign) 6
Step-by-step explanation:
Walk through the problem:
"subtract 10 from 36." = "take ten away from 36." = "36 - 10."
"then divide by 6." = "Divide 36 - 10 by 6." = "(36 - 10) divided by 6."
Answer:
4
Step-by-step explanation:
The computation is shown below:
Given that
There are total number of students i.e. 48
The ratio at present is 4:1
Now the computer needed to make the ratio be 3:1
So let us assume the number of students be 4x
And, the number of computers be x
So the 4x = 48
x = 12
So the computer be 12
Now the new ratio is 3:1
Students be 3x
And, computers be x
So
3x = 48
x = 16
Now the more computer needed is
= 16 - 12
= 4
hence, this is the answer but the same is not provided in the given options
