Oh, dude, like, totally! So, the numbers that multiply to get 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. It's like a big ol' party of factors hanging out together multiplying away. So, yeah, those are the cool cats that make up 80.
Multiply both numbers by 20 to read 80/100... 80/100 = 0.80
Those two numbers would be 80 and 40. 80*40=3200 80+40=120
To multiply mixed numbers, you need to convert them to improper fractrions, multiply and then convert them back to a mixed number. For example: 2 1/2 x 5 1/3 = 5/2 x 16 /3 numerator 5 x 16 = 80 denominator 2 x 3 = 6 so now you convert 80/6 into a mixed number 80 / 6 = 13 and 2/6 or, reduced, 13 1/3.
Multiply 80 by 1.05 to increase by 5%.
Two numbers with a difference of 5 have a product of 6800. x and (x + 5) are our numbers. Let's multiply them together. (x) (x+5) = x2 + 5x That is equal to the 6800 specified. x2 + 5x = 6800 >> x2 + 5x - 6800 = 0 (x + 85) (x - 80) = 0 x + 85 = 0, so x = -85 (this in not a correct answer - it has the wrong sign) x - 80 = 0, so x = 80 (a correct answer, and one of the two numbers we need) Since x = 80, x + 5 = 85 Our numbers are 80 and 85. Let's check. 80 times 85 = 6800. Our work checks.
160
80
-1
I believe that means that you are supposed to multiply the numbers.
-96
-82
10 8
1x80, 2x40, 4x20, 5x16, 8x10
They are 40 and 40
-20 and 80 -20*80=-1600 -20+80=60
80 = 2 x 2 x 2 x 2 x 5
There aren't two whole numbers that satisfy those conditions. If that was -80, you could use 8 and -10.
