Plank of wood 2 metres long. cut into two lenghts. longer piece is four times the lenght of shorter piece. how long is each lenght?


It is solved by writing an equation
If the shorter piece is y cm, then the the longer piece would be 4y which is four times the shorter length. The total of these 2 together is 2meters or 200 cm, Now write the equation (2 pieces together is 200cm)

y + 4y = 200
5y =200
y =40
Since we have taken the lengh of shorter piece as y,
Shorter piece=40 cm OR 0.4m
Longer piece =160cm OR 1.6m
I have written the steps in detail for you to understand the process
Good luck

Longer piece= 160cm

I am a three-digit number. I am less than 200. I am divisible by 12, and by 9. My units digit is less than my tens digit.


One way to solve this is:

Start at 108, which is the first 3 digit number divisible by both 12 and 9.
Then continue adding twelve until you find a number which matches all your criteria.
You will find the answer to be 180.

180 / 12 = 15
180 / 9 = 20
0 < 8

Choose four digits, all different, and place them in a 2x2 grid so that the numbers across and down total 200. How do I do it?


A two by two grid forms four quadrants. In the upper left quadrant, place a 4. In the upper right quadrant place a 2. In the lower left quadrant, place an eight. In the lower right quadrant place a 5. Horizontally, the numbers 42 and 85 are formed. Vertically, you form the numbers 48 and 25. The sum total of these numbers is 200. 42 + 85 + 48 + 25 = 200.

There is a sequence and it is 2,8,18,32,50,72 what is the fiftyiest number


The pattern for this sequence is that the difference between one number and the next is four more than the difference between that number and the previous one.
For example:
8 - 2 = 6
18 - 8 = 10
32 - 18 = 14
50 - 32 = 18

So the sequence is:
2, 8, 18, 32, 50, 72, 98, 128, 162, 200, 242, 288, 338, 392, 450, 512, 578, 648, 722, 800, 882, 968, 1058, 1152, 1250, 1352, 1458, 1568, 1682, 1800, 1922, 2048, 2178, 2312, 2450, 2592, 2738, 2888, 3042, 3200, 3362, 3528, 3698, 3872, 4050, 4232, 4418, 4608, 4802, 5000, ...

So the 50th number in the sequence is 5000
