Answer:
30
Step-by-step explanation:
Let number of tetras be "t"
number of guppies be "g"
number of minnows be "m"
Ratio of tetras to guppies is 4:2, or reducing, 2:1. Thus we can write:
Ratio of minnows to guppies is 1:3, so we can write:
or, m = g/3
Also, total there are 60 fish, so we can write:
t + g + m = 60
or
2g + g + g/3 = 60
Solving this, we can solve for g. Shown below:
Now, finding t and m:
m = g/3 = 18/3 = 6
m = 6
and
t = 2g
t = 2(18)
t= 36
There are 36 tetras and 6 minnows. So, there are
36 - 6 = 30 more tetras than minnows
The answer is 52.5 because you are suppose to multiply each number in pairs. First multiply 21/61 times 5/8.Then you will get 105/488. Multiply 105/488 times 244/1 which equals 25,620/488. Simplify to the lowest form which equals 6,405/122. Divide 6,405 divided by 122. The answer will be 52.5. That is how you will get the answer.
Answer:
= 6 typists
Step-by-step explanation:
Well, 2 can type 2 in 2 mins,
So, 1 can type 2 in 4 mins.
So, 1 can type 18 in 36 mins.
So, 2 can type 18 in 18 mins.
So, 6 can type 18 in 6 mins.

297.3 to 295.?
to get to 297.3 from lets say 295.0 you need 2.3 more so a tenth is 0.1 so divide 2.3 by 0.1. you'll get 23 as the answer.
