I believe that means that you are supposed to multiply the numbers.
10 percent off 80 = 7210% off of 80= 80 - (10% * 80)= 80 - (0.10 * 80)= 80 - 8= 72
The GCF of 10 and 80 is 10
The result of the equation - 130 plus 80 plus 10 plus 80, is found as follows;130 + 80 + 10 + 80= ( 130 + 80 ) + 10 + 80= 210 + ( 10 + 80 )= 210 + 90= 300Answer = 300
The LCM is: 80
10
80 + 10 = 90 - 0 or 80 + 10 = 90 is true
Since 80 is a multiple of 10, it is automatically the LCM.
80 divided by 10 is 8
10 * 80 = 800
10 is 1/8 of 80
12.5 percent of 80 = 10 12.5% of 80 = 12.5% * 80 = 12.5%/100% * 80 = 0.125 * 80 = 10
The least common multiple of 8 , 16 , 10 = 80
