8(5+4)+7 = 79
5 times
4 + (-2) + 5 = 7 BECAUSE adding a negative number is the same as subtracting the number, so 4 + (-2) = 2 and 2 + 5 = 7
To change 32/7 into a mixed number, divide 32 by 7 and the remainder will be the fraction: 32 ÷ 7 = 4 r 5 = 4 5/32
7 just 7
LCM(4, 5, 7) = 140
140. Multipy 5 and 7, then multiply that by 4.

well, no number goes int 5 or 7 that can also go into 8 or 4.
the lowest number i can think of is 840
4 5/7
Any multiple of 140
4/4*5*7 = 1*5*7 = 5*7 = 35
It is: 4+7+5+4+5 = 25/5 = 5 which is the average number
Their LCM is 280
Each number will divide into 420 with no remainder
