80% of 63 is 50.4
(17 + 63)/2 = 80/2 = 40
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.'
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
(17 + 63)/2 = 80/2 = 40
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.
3 is one such number.
7x9=63
