The smallest number that both 63 and 80 can be divided evenly by is their least common multiple (LCM). To find the LCM, we first calculate the prime factorization of each number: 63 = 3 x 3 x 7 and 80 = 2 x 2 x 2 x 2 x 5. The LCM is the product of the highest power of all prime factors involved, so LCM(63, 80) = 2 x 2 x 2 x 2 x 3 x 3 x 5 = 720. Therefore, 720 is the number that both 63 and 80 can be evenly divided by.
80% of 63 is 50.4
After putting them in order, cross out the 'ends' First 58 and 80 Then 58 and 74 You are left with 63 and 69 The median number is 66. The median is the number in the 'middle.'
To calculate the mean of the numbers 56, 77, 68, 63, 69, 68, 80, 71, and 63, first sum them: 56 + 77 + 68 + 63 + 69 + 68 + 80 + 71 + 63 = 616. Then, divide the total by the number of values, which is 9. Thus, the mean is 616 ÷ 9 = 68.44.
The greatest common factor is 63
HCF(63, 35) = 7
80% of 63 is 50.4
63% of 80= 63% * 80= 0.63 * 80= 50.4
63/80 = 63 ÷ 80 = 0.7875
Seven goes into both 63 and 77
After putting them in order, cross out the 'ends' First 58 and 80 Then 58 and 74 You are left with 63 and 69 The median number is 66. The median is the number in the 'middle.'
3 goes into 36 and 63 evenly.
To calculate the mean of the numbers 56, 77, 68, 63, 69, 68, 80, 71, and 63, first sum them: 56 + 77 + 68 + 63 + 69 + 68 + 80 + 71 + 63 = 616. Then, divide the total by the number of values, which is 9. Thus, the mean is 616 ÷ 9 = 68.44.
7x9=63
63/80 is in lowest terms. 80=2x2x2x2x5 2 and 5 do not got into 63 without a remainder.
3 is one such number.
