Answer:
63 red marbles.
Step-by-step explanation:
Because the probability of drawing a red marble is 7/8, the number of red marbles = 7/8 * 72
= 7 * 9
= 63.
Money makes for nice decimal examples.
If you had $1.50, and you wanted to split it among three people, you would have :
1.50 divided by 3 (which would be $0.50 each)
These 5 bottles with lemonade which contains 150 millilitres in each bottle so it would be 150 x 5 to find how many millilires there is in all
3 x 500
+
3 x 80
+
3 x 4
=
1,752
By expanding 584 and multiplying the different parts by 3, the multiplying is simplified. Then you just have to add together the multiplication you did.
