8 = 4*2
So 5*8 = 5*(4*2) which, by the associative property, = (5*4)*2
= 20*2
Can you do 20*2 more easily than 5*8?
If not, you need another round of associate property.
20 = 10*2
So 20*2 = (10*2)*2 = 10*(2*2) = 10*4
And if you cannot do 10*4 then this question is beyond you anyway and knowing 5*4 is not going to help.
What else can I help you with?
To find 6X8 can you use the facts about 5X4 and 1X4?
Yes, you can use the facts about 5x4 and 1x4 to find 6x8. First, recognize that 6x8 can be broken down into (5+1)x8, which equals 5x8 + 1x8. Since 5x8 is the same as 5x(4+4), you can calculate that as 5x4 + 5x4, and then add 1x8 (which is 8). This way, you can use the known facts to help find the answer.
