Prime factors are numbers that are: prime, and multiply to make the number you want, in this case 75. 75 as a product of prime factors would be, 3 x 5 x 5; if you work this out, the result is 75.
To find the HCF you first have to write the numbers as their prime factors: 36 = 2x2x3x3 75 = 3x5x5 The next step is to identify any common prime factors. In this case both numbers have 3 as a prime factor. Thus the HCF is 3. To find the LCM you need to multiply the numbers together and divide by the HCF. 36x75/3 = 900 Thus the LCM of 36 and 75 is 900.
There is an endless list of numbers that add together to give 175, an example is 75+60+40.
Just multiply the two together to get area. This would be 900 square feet.
You take the .8 and multiply it by 100 because a percent of something is one hundredths of 1. For example, 75 cents is 75 one hundredths of a dollar. 75 cents is written as .75 in decimal form. .75 (75 cents) is 75% of 1 dollar. To change 75 cents or .75 to a percent, you just multiply it by 100 which .75 times 100 is 75. So, to find out what .8 is as a percent you just multiply it by 100 which is 80.
1 x 75 3 x 25 5 x 15

15*5
You can multiply 5 by 15 to get 75.
3 and 25
To find the product of 0.0198 and 75, you simply multiply the two numbers together. This can be done by multiplying 0.0198 by 75, which equals 1.485. Therefore, 0.0198 times 75 is equal to 1.485.
-5 and -15 because -5 + -15 equals -5 - 15 which is -20 and -5 multiplied by -15 = 75 (two negatives multiply to make a positive)
375 = 75 X 5(product is the result when you multiply the multiplicand and multiplier)
5x15 = 75

(-225,1)(-75,3)(-45,5)(-25,9)(225,-1)(75,-3)(45,-5)(25,-9)(-15,15)
2 x 75 = 150
