Three numbers whose product is 64 are 2, 4,
and 8 because 2 x 4 x 8 = 64.
a. Find three numbers whose product is 2.4.
Just divide it by something and then divide that by something.
Start by dividing 2.4 by something, say 3.
2.4 ÷ 3 = 0.8
Now divide 0.8 by something, say 2
0.8 ÷ 2 = 0.4
So 0.4 × 3 × 2 = 2.4
You find another set of three numbers by dividing twice like that.
----------------------------------
c. Find three numbers whose sum is 2.4.
Just subtract something and then subtract something from what you get.
2.4 - 0.9 = 1.5
Subtract something from that:
1.5 - 0.7 = 0.8
So 0.8 + 0.7 + 0.9 = 2.4
-----------------------------
You find another set of three numbers by subtracting twice like that.
