This seems like a simple conversion problem. 1m=?cm and 1cm=?m.
Since this uses the metric system, you know the general layout of the prefixes: K H D M d c m. I remember this as King Henry died Monday drinking chocolate milk, but as long as you remember it you're good.
Let's look at 1m. Centimeters is two places away from it
K H D (M) d (c) m
This means you move the decimal place to the right two times, so 1 meter is equal to 100 centimeters.
For 1 cm, the meter position is two places away. This means we have to move the decimal place to the left two times. So, 1 centimeter is equal to 0.01 meters.
Step-by-step explanation:
total students=99
finished entering marks =9\11
let the entered number be x
now,
"x=9\11×99
x=9×9
x=81
again,
99-81=18
the remaining number of students is 18
If you would like to find 2 numbers which you can add up to get 24 and multiply to get -25, you can calculate this using the following steps:
a + b = 24 ... b = 24 - a
a * b = -25 ... a * (24 - a) = -25 ... 24 * a - a^2 = -25 ... 0 = a^2 - 24 * a - 25
0 = (a - 25) * (a + 1)
1. a = 25
2. a = -1
b = 24 - a
1. b = 24 - 25 = -1
2. b = 24 - (-1) = 25
The numbers you are looking for are -1 and 25.

Alright 21 miles per hour. We know that there are 60 minutes in an hour. So this is basically saying 21 miles per 60 minutes. To find the rate for miles per minute, you divide 21 by 60 which is 0.35.
In one minute the cyclist rides 0.35 miles
In two minutes the cyclist rides 0.7 miles
